About Me:

Hi, I am Eldho. I hail from the coastal town of Kochi in Southern India. I am a PhD reseacher at the Airborne Trace gas measurements and Mesoscale modelling (ATM) group lead by Dr. habil. Christoph Gerbig. I joined the institute on March 2020 through the International Max Planck Research School for Global Biogeochemical Cycles (IMPRS-gBGC) program and I am admitted to the Faculty of Chemisty and Earth Sciences of the Friedrich Schiller University Jena. Currently, I am also holding the position of the PhD Representative of the Biogeochemical Signals Department (from September 2020).

PhD Project:

• Constraining the greenhouse gas budget of the Indian subcontinent

The project focuses on the greenhouse gas budget of the Indian Subcontinent, an area of extensive agriculture and rapid social change, both of which influence carbon fluxes and air quality. Unfortunately at present there are very few atmospheric measurements available over the region, which results in highly uncertain carbon budget estimates, often as high as ~100-150%. This project aims to reduce these uncertainties by quantifying the carbon fluxes over India using an inversion scheme and to develop cost-effective methodology to augment the existing network of continuous GHG concentration measurement sites (tall towers). Towards achieving this goal, a high resolution Bayesian inversion framework will be designed by utilizing a combination of synthetic data as well as existing ground-based and satellite data.

The project is in close collobaration with the Max Planck partner group of Greenhouse gas Modeling and Applications (GMA) group at Indian Institute of Science Education and Research (IISER) Bhopal, India headed by Dr. Dhanyalekshmi Pillai. The project also colloborates with the Friedrich Schiller Univerity (FSU), Jena with Prof. Dr. Kai Uwe Totsche co-supervising the project. The funding is jointly provided by the DAAD (German Academic Exchange Service) scholarship and the Max Planck Society.
