    A long way for a little satellite

    The PROBA-1 satellite, a technology demonstrator later turned into an Earth observation mission – and just a cubic metre in volume – is reaching 20 years of continuity, making it a huge success.

    Assessment of Canopy Structure and Heterogeneity from Multi-Angular CHRIS-PROBA Data

    The spaceborne ESA-mission CHRIS-PROBA (Compact High Resolution Imaging Spectrometer-Project for On-board Autonomy) provides hyperspectral and multi-angular data of selected terrestrial targets (Barnsley et al. 2004). For vegetated surfaces, the spectral information content of CHRIS data may yield the biochemical and biophysical properties of a vegetation canopy, while the directional component may deliever additional information on its canopy structure. Here, the multi-angular CHRIS observations are investigated and related to surface structure using the parametric RahmanPinty-Verstraete (RPV) model.

    Aura OMI complete NASA dataset

    The OMI observations provide the following capabilities and features: A mapping of ozone columns at 13 km x 24 km and profiles at 13 km x 48 km A measurement of key air quality components: NO2, SO2, BrO, HCHO, and aerosol The ability to distinguish between aerosol types, such as smoke, dust and sulfates The ability to measure aerosol absorption capacity in terms of aerosol absorption optical depth or single scattering albedo A measurement of cloud pressure and coverage A mapping of the global distribution and trends in UV-B radiation. The OMI data are available in the following four levels: Level 0, Level 1B, Level 2, and Level 3. Level 0 products are raw sensor counts. Level 0 data are packaged into two-hour "chunks" of observations in the life of the spacecraft (and the OMI aboard it) irrespective of orbital boundaries. They contain orbital swath data. Level 1B processing takes Level 0 data and calibrates, geo-locates and packages the data into orbits. They contain orbital swath data. Level 2 products contain orbital swath data. Level 3 products contain global data that are composited over time (daily or monthly) or over space for small equal angle (latitude longitude) grids covering the whole globe.
