I am Saqr Munassar, from Yemen. I started working from the 1st of July, 2018 as a PhD candidate in the ATM working group led by Christoph Gerbig along with the SRS group led by Julia Marshall. I conduct a project on developing preoperational mesoscale inverse modelling system for quantifying GHGs’ sources and sinks.

I moved to Germany at the end of 2014 for pursuing the Master studies at the Environmental Physics Institute (IUP), University of Bremen. My Master’s thesis was specified for studying the cloud impacts on tropospheric retrievals observed from space-based remote sensing monitoring. After being awarded the Bachelor degree with the first rank in Physics at the University of IBB (IBB, Yemen), I had been appointed as an academic member in the Physics department since 2010. During the period 2010 – 2014, I was working on teaching a couple of practical physics courses as well as joined a research team carrying out projects on nanomaterials and their application in the environment (resulted in publishing two scientific papers).

Currently, my research interest is mainly focused on enhancing the quantification of the GHGs exchange between the surface and the atmosphere, in particular Bio-Atmospheric regional fluxes, using the state-of-the-art of numerical models. Additionally, developing cloud product algorithms for satellite measurements is an interest for a better quantification of tropospheric retrievals, including GHGs, with a good tempo-spatial resolution.

I look forward not only to learning from such a scientific leading constitution but also to exchanging the knowledge and expertise in relation to promoting the protection of climate system and vulnerable ecosystems on our fascinating Earth’s Planet.

+++ Ambarchik video +++
26 January, 2018

The Arctic is warming due to climate change. What are the consequences for greenhouse gases in the atmosphere? Friedemann Reum and Mathias Göckede from the Max Planck Institute for Biogeochemistry want to find out. They measure greenhouse gas concentrations in the air on-site - in the remote locality Ambarchik, at the Siberian coast of the Arctic Ocean. With their data they calculate how much carbon dioxide and methane escapes from the permafrost soils of the Siberian Arctic into the atmosphere.

Friedemann Reum and Mathias Göckede explain their research on permafrost in a remote locality in the Siberian Arctic in this new educational video on Youtube (English version/German version)

Hello! My name is Michał Gałkowski (but please feel free to call me Mike), and I’ve recently joined Airborne Trace Gas Measurements and Mesoscale Modelling group (ATM) as a post-doc. My tasks will be associated with the AIRSPACE project that aims at providing very detailed information on methane and carbon dioxide fluxes on regional scales, using the aircraft-based measurements and state-of-the-art modelling techniques applied at European emission hot-spots (like Silesian Coal Basin in Poland).

I’ve completed my PhD thesis in late 2015 at the AGH University of Science and Technology in Kraków (also in Poland). In it, I focused on researching regional loads and emissions of nitrous dioxide using both measurement and modelling methods. During last two years I’ve continued to work at the University, focusing on studying the emissions and atmospheric transport patterns of other atmospheric pollutants, mainly CH₄ and PM10. I am very much looking forward to this new adventure, especially since it fits so well with my scientific interests.

Privately, I love reading books and watching films. I also enjoy discussions about history very much, and I am always keen on learning new things. German language is at the top of my list now!

+ Workshop on building research at ATTO
16 October, 2017

On 4 and 5 October, we participated at the ATTO workshop hosted by the National Institute of Amazonian Research (INPA; Manaus, Brazil). The main objectives were to present current work related to the ATTO site and plan future joint research at and around ATTO.

The workshop participants agreed to produce a new science plan that integrates research on energy, water, aerosols, and greenhouse gases exchange between the central Amazon forests and the atmosphere, and explores the role of volatile organics and trace gases on cloud formation and atmospheric chemistry. Over the next 20 years, ATTO scientists aim at providing new knowledge on the role of the Amazon forest in the global climate system and its response to changing climate. see press release

+ We welcome Amir Hossein Abdi
15 September, 2017

Hello! I am Amir Hossein Abdi, an M.Sc. Environmental Science and Engineering graduate from Istanbul Technical University. I am currently doing my Ph.D. under the supervision of Dr. Julia Marshall on the project “Inverse Modeling of Atmospheric Methane Focusing on active remote sensing measurements.” Prior to my job in BGC, I worked on an air quality modeling project funded by Turkish Scientific and Technological Research Council. In that job, I was performing the simulations by Weather Research and Forecasting (WRF) model, Community Multiscale Air Quality (CMAQ) modeling system and the emission processing over Europe and Turkey as the nested domain. I evaluated the European Monitoring and Evaluation Programme (EMEP)SO2 Emissions for Turkey using ground-based and satellite observations.

My other areas of interest include air quality modeling, atmospheric modeling, and trace gas remote sensing. In my spare time, I am most amused by history and biography reading, movies, card games, backgammon, and sports like climbing, swimming, skiing, and table tennis.

+ We welcome Xiaoyang Chen
14 September, 2017

Hello everyone! My name is Xiaoyang Chen. I am from Tianjin, China. I am very happy to work as a PhD student here. Before moving to Jena, I studied atmospheric science for my BSc, and meteorology for my MSc, both at Nanjing University of Information & Science and Technology(NUIST). My work has mainly concentrated on climate change over the Tibetan Plateau. I used a statistic downscaling method to project the temperature and precipitation under three RCP scenarios. I also studied the ocean-atmosphere interaction and the effect of Indian Ocean sea surface temperature on on the Tibetan Plateau precipitation.

I am now working in Jost Lavric's group, where I will be involved in the ATTO project. My research may focus on the greenhouse gas budget and its effect on the ecosystem. Sometimes I will also go to the Amazon for field work in the next three years.

+ We welcome Shujiro Komiya (Komi)
13 September, 2017

Hello everyone. I’m Shujiro Komiya and I’m from Japan. If you don’t mind, please call me Komi. Since last month, I have joined the Tall Tower Atmospheric Gas Measurements Research group as a new postdoc. In this research group, I will mainly work on atmospheric vertical profiles of water stable isotopes (δ2H and δ18O) at ATTO tall tower in Amazon forest to clarify how water is (re-)cycled in Amazon basin and forest canopy.

In my M.Sc., and Ph.D. studies at Meiji University in Japan, I developed a relaxed eddy accumulation (REA) system, and investigated methane (CH4) and carbon dioxide (CO2) dynamics in rice paddy fields in temperate Japan and Thailand using REA or Eddy Covariance methods. I also studied air-sea CH4/CO2 fluxes over the Northern Pacific Ocean and Japan Sea using REA method. In my daily life, I love traveling, cooking and playing sports such as badminton, soccer, baseball etc. Now, I usually join MPI-Jena-Football, and enjoy playing soccer.

+ We welcome Martijn Pallandt
13 March, 2017

Hello everyone, my name is Martijn Pallandt. Last month I was welcomed to IPAS group of the BSY department formerly headed by Martin Heiman. Before moving to Jena, I used to live in the Netherlands where I studied biology/ecology for my BSc, and earth system science for my MSc, both at Wageningen University. In-between I made a little detour to the University of Groningen and the NIOZ for a minor in marine biology. After which I worked as a research at the Vrije University Amsterdam.

The complexity of natural systems and their myriad feedbacks is what drew me to ecology and earth system science. Particularly marine and arctic environments interested me as they are still some of the least understood environments on earth. My PhD research here will be part of the Integrated Arctic Observation System (INTAROS) project where I will focus on improving our understanding of the Arctic greenhouse gas budgets through the evaluation of the existing pan-Arctic atmospheric tower net work. Furthermore, I will contribute in upgrading the Ambarchik site with an automated flask sampling system.

In my free time I enjoy sports like bouldering, martial arts and on vacation skiing and scuba diving. Additionally I like games of all sorts: computer games, card games miniature games, you name it.

+ NASA ATom mission returns to Ascension Island
February 14, 2017

The NASA DC-8 aircraft arrived on Ascension Island yesterday. It was the 2nd visit during the NASA Atmospheric Tomography mission (Principal Investigator: Steve Wofsy, Harvard University). During the first visit in August 2016, the DC-8 already measured two profiles of CO2, CH4, and CO from ~12 km to the ground. These were used to check the calibration of the Ascension Island TCCON instrument vs. the WMO scale. A successful aircraft-calibration is a prerequisite to promote a TCCON station from "provisional" to "full" status. The DC-8 will stay on Ascension for one day and then continue on to the Azores. It will probably return to Ascension in October 2017. The data analysis on both sides will take about 6 months.

Hello everyone, my name is Sandra Bölck and I am the new PhD student in the permafrost research projects supervised by Mathias Goeckede and Martin Heimann. During my Bachelor I studied “Geographical Sciences” at the Freie University of Berlin, where I continued with my Masters programme in “Environmental Hydrology”. I conducted my master thesis in collaboration with the Leibnitz-Institute of Freshwater Ecology and Inland Fisheries in Berlin. My research focus was mainly on the transition zone between groundwater and surface water at an oligotrophic lake in northern Brandenburg (Lake Stechlin). Based on small-scale field measurements, multi-temporal and spatial pattern of chemical parameters such as nitrate, iron and chloride as well as of isotopic compositions of hydrogen and oxygen were analysed. Exfiltrating conditions at the study site could be proven by piezometer measurements (Darcy's law) and an electromagnetic seepage meter in order to estimate the impact of groundwater on the lake. In 2015, I was employed as a hydrologist at an environmental consultant agency in Cork, Rep. of Ireland. The application of the groundwater and transport model Visual Modflow to estimate the longevity and the extent of a contaminant plume was my main task. Furthermore, the visualisation, analysis and assessment of potential impacts on the environment were parts of my work. My current project is focused on the hydrology and its influences on the carbon cycle processes in the permafrost region around Chersky, Northeast Siberia. As core elements of my research, I am planning to study fine-scale patterns in water transport within our field site on the floodplain of the Kolyma River and quantify the lateral export of Carbon through a drainage system.

+ First successful test mission with greenhouse gas measuring instruments on board of HALO
June, 2015

A first test mission with the Jena Instrument for Greenhouse Gases (JIG) on board of the German High Altitude and LOng Range (HALO) research aircraft was completed successfully in May 2015. The mission was conducted to test an active remote sensing system measuring column abundances of CO₂ and CH4, developed by the LIDAR group at the DLR Institute of Atmospheric Physics. This system is a so-called airborne simulator for the upcoming MERLIN (Methane Remote Sensing LIDAR Mission) satellite. MERLIN is a German-French climate mission, scheduled currently for launch in 2019. The airborne LIDAR system uses pulsed laser light, and detects the backscatter from the surface or from clouds as a function of time, providing path length information as well as absorption along the path. The goal of the mission was to evaluate the CO₂/CH4 LIDAR with the in-situ observations made by JIG, which was originally designed for operation on board of a fleet of passenger aircraft within the ESFRI project IAGOS (In-service Aircraft for a Global Observing System). JIG uses Cavity Ring-Down Spectroscopy (CRDS) to measure the greenhouse gases CO2 and CH4 as well as CO and H2O. Measurements are referenced to WMO (World Meteorological Organization) calibration scales by means of in-flight calibration using compressed gas cylinders.

After a first test flight ensuring no interference of the measurement systems with the aircraft operation, the mission targeted areas with different surface characteristics to assess the impact on the LIDAR signal. Furthermore, different methane source areas such as the Po valley with intensive agriculture and livestock, and the Silesian coalmines in Poland, were overflown by HALO in order to evaluate the potential of the scientific payload for source detection and quantification. Both instruments performed well throughout the five flights, with a total flight time of about 20 hours. First preliminary data by JIG have been processed; LIDAR data processing is ongoing at the moment. Future missions planned for 2017 will use a payload augmented by passive remote sensing instruments and by flask a sampling system to allow for analysis of air samples for their isotopic composition, which further helps identifying specific processes contributing to GHG emissions.

My name is Dhanya Pillai, and I recently joined the BGC-Systems department (in SRS group) as a Postdoc. As many of you have already realized, I’m not essentially a newcomer to the institute as I had been formerly working here (in ATM group) as a PhD student. At the institute, you may find me in A3.006.

My research interest, in a broad sense, is to explore the usability of atmospheric measurements of important greenhouse gases to estimate the regional distribution of their sources and sinks to a high degree of certainty, which is important to manage changes in the carbon cycle. Before joining here, I spent a few years working as a postdoctoral researcher at the Institute of Environmental Physics at the University of Bremen, mainly focusing on the regional atmospheric modeling activities related to CarbonSat, a candidate to be ESA’s next Earth Explorer mission. In my current role, I will be involved in the project GAIA-CLIM, dealing with the robust assessment of gaps in the sub-orbital measurement networks used for calibration and validation of satellite-based measurement of atmospheric composition and state. In addition to this, I will start working on OCO-2 observations in order to examine how we can best utilize these data to provide realistic flux estimations through inverse modeling.

Besides all this, I enjoy spending my time with family and friends, and exploring nature. I'm truly excited to be back to the institute after a couple of years and looking forward to working with many of you again. Thanks to everyone for being so welcoming and extending your support.

+New Atmospheric Carbon Observation Station established in Ambarchik, Russia
July 16 - Aug 8, 2014

In late July and early August 2014, a new station for continuous monitoring of atmospheric carbon dioxide and methane was established in Ambarchik (69.6 N, 162.3 E), a rural locality in Siberia at the coast of the Arctic Ocean. The station is equipped with a tower of 27m height and a Picarro G2301 analyzer for high precision measurements of CO2, CH4 and H2O, along with meteorological instrumentation. The Ambarchik station will help shed light on permafrost-related processes in the global carbon cycle. Due to its coastal location it is capable of capturing atmospheric signatures of carbon exchange processes from the Arctic Ocean and from the Siberian Tundra.

The project is part of the PhD-project of Friedemann Reum of the IPAS-group led by Mathias Göckede. Many thanks for the successful conclusion of the field trip go to Martin Hertel, Olaf Kolle, Jost Lavric￾, Nikita Zimov, Sergey Zimov and Martin Heimann.

+ Annual Joint NDACC-IRWG & TCCON Workshop 2014
May 12-15, 2014

The largest science meeting of the ground-based infrared atmospheric remote sensing community will take place in Bad Sulza from May 12-15. More than 85 specialists from 16 countries will discuss the latest developments in the Infrared Working Group (IRWG) of the Network for the Detection of Atmospheric Composition Change (NDACC) as well as the Total Carbon Column Observing Network (TCCON).

Both groups use high-resolution infrared measurements to measure atmospheric trace gases in the atmosphere from the ground up to an altitude of ~100 km. IRWG has been monitoring the atmospheric composition of many trace gases - especially ones that are related to the ozone layer - for more than 30 years. TCCON aims at very high precision measurements of greenhouse gases and has become the de facto reference for all current and future satellite greenhouse gas observing missions.

The meeting has been organized by the Atmospheric Remote Sensing Group of the Max Planck Institute for Biogeochemistry (MPI-BGC), Jena. Some of the participants will also visit MPI-BGC on May 16.

April 2014

My name is Sebastian Sippel and I joined the institute to pursue my PhD with Martin Heimann and Miguel Mahecha. My work will be to generate a large ensemble of terrestrial biosphere model simulations, in order to better assess and constrain the risk of extreme impact events. The ensemble simulations will be driven by a large meteorological ensemble (climateprediction.net) and will be performed using (at least) one biosphere model and/or impact model. The modelling study is conducted in cooperation with the climate research group at the University of Oxford. Before coming to Jena, I finished a Master degree in “Geoecology” (Univ. Bayreuth) and “Environmental Change and Management” (Univ. Oxford). The recent Master thesis focussed on the evaluation of carbon dynamics in models using statistical complexity measures, a non-linear technique to characterize the temporal dynamics of time series. In my leisure time, I enjoy sports: I’m a passionate runner and cyclist and look forward to explore Jena and Thuringia!

From August 2013, when the ship’s cruise started in Walvis Bay (Namibia), until its arrival in Mindelo (Cape Verde) in March 2014, we will continuously measure atmospheric carbon dioxide and methane concentrations. The goal of this undertaking is to supplement various on-board measurements of our project partners, to complement atmospheric measurements at the Namib Desert Atmospheric Observatory (MPI-BGC) and the Cape Point atmospheric observatory (SAWS), to study the influence of the Benguela upwelling on the atmosphere, and to learn more about the latest atmospheric interhemispheric gradient.

+ Ascension Island operational again

Sabrina Niebling and Dietrich Feist just returned from a three-week maintenance visit to the TCCON station on Ascension Island. About 100 kg of spare parts and equipment had been sent ahead to replace items that had suffered badly from sea salt corrosion during the first year of operation. Most of the new parts were re-designed to make them less susceptible to the volcanic dust and sea salt that is ubiquitous on the island. The most critical parts were two optical mirrors that guide sunlight into the instrument. Various types of optical coatings have been tested but none of them was able to withstand the harsh environment for more than a few weeks. The new mirrors are made of stainless steel. So far, they how no signs of degradation.

+ The ZOTTO “bunker” gets new isolation
29 August 2011

After a joint German-Russian effort under supervision of Steffen Schmidt, work on the new isolation of the ZOTTO “bunker” was concluded on Monday 22 August 2011. About 1000 m3 of sand that covers the shelter at the foot of the ZOTTO mast and protects it from the harsh Siberian meteorological conditions had to be moved twice. ZOTTO instruments are now safe from humidity and fungal attacks for many years to come.
