Blue Marble images on the IPCC 4th assessment report (2007)

The Blue Marble western and eastern hemispheres by Reto Stöckli (NASA Earth Observatory) are displayed to the left as printed on the front cover of the IPCC (Intergovernmental Panel on Climate Change) 4th assessment WGI report “The Physical Science Basis”.   These images integrate land, ocean, sea ice and clouds into a visual representation of …

The European Heat wave of 2003 as seen from MODIS

Europe was experiencing a historic heat wave during the summer 2003. Compared to the long term climatological mean, temperatures in July 2003 were sizzling. Figure 1 below shows the differences in day time land surface temperatures of 2003 to the ones collected in 2000, 2001, 2002 and 2004 by the Moderate Resolution Imaging Spectroradiometer (MODIS) …

PhD Thesis

Modeling and observations of seasonal land-surface heat and water exchanges at local and catchment scales over Europe (Doctoral thesis ETH No. 15742) The land surface plays an important role in the global climate system, because it interacts dynamically with the atmosphere through manifold feedback mechanisms on a wide range of spatial and temporal scales. While …

The European Fourier-adjusted and Interpolated NDVI (EFAI NDVI)

The EFAI NDVI is a high resolution land surface parameter dataset for climate modeling and mesoscale weather simulations. It was derived from the 20 year long NASA/NOAA AVHRR Pathfinder NDVI dataset, which is available in 10 day temporal and 0.1 degree spatial resolution for global area coverage. The variability of vegetation state and function motivates …

NDVI Measurements with Simple Radiometric and photographic Methods

A remote sensing tutorial for teachers and students In July 2003 our institute IACETH (Insitute for Atmospheric and Climate Science, ETH Zurich) offered a field course on hydrology and climate science taking place in our research catchment “Rietholzbach”. In this course I teached students how to measure the surface radiation balance using pyrano- and pyrgeometers. …
