Land use change in Sumatra
The Swiss NGO Paneco is engaged in Sumatra (Indonesia) where anthropogenic land use changes threaten local fauna and flora. The collaboration with Paneco has started with a small project that aimed at diagnosing rainfall intensity of a storm from TRMM 3B42 space radar data due to a lack of locally available rain gauges. The project …

Blue Marble Next Generation
The Blue Marble Next Generation (BMNG, 2005) is a cloud-free global satellite data set offering great spatial detail. It spans a longer data collection period than the original Blue Marble from 2000 and 2002. The original Blue Marble was a composite of four months of MODIS observations with a spatial resolution (level of detail) of …

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 …

Aura satellite launch & deploy
Aura is a earth observing satellite and it is part of NASA Earth Observing System (EOS). Aura’s four instruments study the atmosphere’s chemistry and dynamics. Aura’s measurements will enable us to investigate questions about ozone trends, air quality changes and their linkage to climate change. Aura’s measurements will provide accurate data for predictive models and …

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. …

Aqua satellite launch & deploy
Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth’s water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. Additional …
