(by Markus Reichstein) Fluxnet Site Elevation derived from ASTER_GDEM2 [0m (white-blue-green-yellow-red) 5860m] (by Ulrich Weber) A Comparison of daily SWdown [2001] between different Meteo Forcing Sets represented as xy-counts within 1by1 Wm-2 boxes [low (white-blue-green-yellow-red) high] (by Ulrich Weber) Nowadays (by Birgitta Wiehl) Why does a blonde need an eraser to use a notebook? To remove the pencil marks after she has written all over it. (by Antje Moffat) Spatiotemporal 'egg boxes'. Artificial periodic datasets to test the spatiotemporal SSA gap filling algorithm. (by Jannis v. Buttlar) This is GAGE while finding the best subset of variables to describe fAPAR anomalies of Africa! Visualization of an evolutionary process (by Enrico Tomelleri) different views [full length go to ftp://ftp.bgc-jena.mpg.de/pub/outgoing/uweber/MPG_Science_Gallery/Animated.mpg] (by Uli Weber) Global Evapotratspiration spinning (by Martin Jung) Spatial scales of a crown caps MDI logo near the red couches as seen after the last MDI barbeque based on a piecewise application of a 2D singular spectrum analysis (by Matthias Forkel) Temporal singular spectrum analysis (SSA) gapfilling. Shown is a gappy artificial time series and SSA reconstructions for each step of the iterative procedure. The lower panel is a magnification of a small part of the series. (by Jannis v. Buttlar) Deviation from the truth: GPML predictive uncertainty hyperplanes VS true deviation contours (by Olaf Menzer) HGP predictive uncertainty hyperplane for NEP daytime summer data measured at DE-Hai (by Olaf Menzer) Meteo gap-filling product quality checks for all FLUXNET sites and performance at site DE-Hai (by Antje Moffat & Olaf Menzer) The 'symphonic' aspects of spectral data analysis. Shown are different aspects of a GAM fit of GPP predicted by climate drivers. The 'ghostly' features are caused by periodic patterns in the data used for gap filling. (by Jannis v. Buttlar) First eigenvalues of a spatial singular spectrum analysis of FAPAR in Siberia (by Matthias Forkel) To what extent are soils important ;) ? (by Enrico Tomelleri) gallery 027 precip Graphical representation of the correlation matrix of 13 highly correlated parameters. In the lower left triangle density estimates of the marginal bivariate distributions are shown (estimated with KDE). In the upper right triangle the linear correlation coefficients are shown. On the diagonal the univariate marginal distributions are shown. Compare also with previous picture. (By Maarten Braakhekke) Sample of 3 highly correlated parameters obtained with MCMC. The isolines on the axis planes and 3D surfaces indicate equal probability density of the marginal bivariate distributions. They have been derived with kernel density estimation. Compare with next figure and find the three corresponding bivariate distributions.

Interested in the workshop? www.bgc.mpg.de/bgc-mdi/index.php/Projects/EcosyAtmosData (created by Nuno and Miguel at www.wordle.net) Model-Data comparison: Residual annual cycles of three terrestrial biosphere models visualized as polar plot. The resiudals are shown interms of 95% confidence envelopes accounting for the uncertainty of subsignal extraction (by Miguel Mahecha). Skewness of mean monthly GPP simulated by the LPJ-DGVM (by Christian Beer) Mean annual GPP of Scandinavian watersheds (by Christian Beer) View distorted by too much looking at remote sensing data, this time around the Puechabon Fluxnet tower (by Anna Goerner) Global bug (seen by Lina Fürst and Miguel Mahecha) Voronoi Mosaic from FLUXNET (planar point set) (by Enrico Tomelleri) Soil moisture content simulated with a Darcy-Richards model (by Maarten Braakhekke) An impressionistic view of ecosystem modelling (by Maarten Braakhekke) Flux fingerprint of the Mediterranean evergreen broadleaf forest Puéchabon operated by CEFE-CNRS Montpellier (Serge Rambal and co-workers). This isopleth diagramm is a visualisation of a whole year of half-hourly net ecosystem carbon exchange, where time of the day is on the x-axis, time of the year on the y-axis and colours code the flux quantity. It is called fingerprint, since each ecosystem usally exhibits very specific patterns. For the Mediterranean ecosystems a drop a activities during the summer period is charracteristic.
