MIPAS is a very high spectral resolution sounder (0.025 cm wavenumber resolution) onboard ESA's Envisat satellite. It provides 59,605 spectral points or channels in 5 bands in the range 685-2410 cm. In the nominal scanning configuration, it gives one scan about every 5o latitude for 17 tangent altitudes between 6 and 68 km. The field of view (FOV) is 3 km in the vertical and 30 km in the horizo...

The ENVISAT Satellite Payload includes the SCIAMACHY instrument designed to measure a number of chemically important atmospheric trace constituents on a global basis. Accurate determination of cloud information out of SCIAMACHY nadir measurements is needed for the retrieval of ozone and other trace gases and it is crucial for more demanding applications like aerosol retrieval and the retrieval ...

In order to quantify real time pasture biomass from SAR image, regression model between ground measurements of biomass and ENVISAT ASAR backscattering coefficient should be built up. An important prerequisite of valid and accurate regression model is accurate grass backscattering coefficient which, however, cannot be obtained when there is speckle. Speckle noise is the best known problem of SAR...

Earth Observation is a powerful tool for the detection of floods. Microwave sensors are typically favored as they deliver data enabling water detection independent of solar illumination or cloud cover conditions. However, scale issues play an important role in radar based flood mapping. Depending on the flood related phenomenon under investigation, some sensors might be more suitable than other...

Wetlands are important ecosystems playing an essential role for continental water regulation and the hydrologic cycle. Moreover, they are sensitive to climate changes as well as anthropogenic influences, such as land-use or dams. However, the monitoring of these regions is challenging as they are normally located in remote areas without in situ measurement stations. Radar altimetry provides imp...
