    SMOS data reveal ecosystems' resistance to drought

    Climate change is rapidly altering the world’s ecosystems, causing extreme weather conditions, such as droughts, to become increasingly frequent. Understanding the factors that contribute to ecosystem resilience to extreme events is vital to develop more effective strategies for climate adaptation and mitigation.

    FSSCat products

    The FSSCat collection provides hyperspectral data coverage over a number of locations around the world, as measured by the HyperScout 2 sensor. The FSSCat hyperspectral data products are comprised of 50 spectral bands, covering a spectral range of 450 – 950 nm with a spectral resolution of 18 nm (at FWHM). Imagery is available with an along-track ground sampling distance (GSD) of 75 m. To ensure a high degree of radiometric accuracy, HyperScout 2 data are validated through comparison with Sentinel-2 data products. The processing level of the data is L1C – calibrated top-of-atmosphere radiance, reflectance or brightness temperature. The raster type of the L1C data product is a GRID – a 2D or 3D raster where the (geo)location of the data is uniquely defined by the upper left pixel location of the raster and the pixel size of the raster, and the projection parameters of the raster (if georeferenced). The third dimension can e.g. be a spectral or third spatial dimension. The L-1C VNIR data product includes a hyperspectral cube of TOA reflectance in the VNIR range, as well as relevant meta-data that adheres to EDAP's best practice guidelines. This product consists of georeferenced and ortho-rectified image tiles that contain spectral reflectance data at the top-of-the-atmosphere. Each image tile contains radiometrically corrected and ortho-rectified band images that are projected onto a map, as well as geolocation information and the coordinate system used. Additionally, each image pixel provides TOA spectral reflectance data in scaled integers, conversion coefficients for spectral radiance units, viewing and solar zenith and azimuth angles, and quality flags.

    Overachieving SMOS mission primed for continued success

    ESA’s Soil Moisture and Ocean Salinity mission (SMOS) was the second Earth Explorer launched in 2009. Over 13 years on, having already vastly exceeded its predicted lifetime and initial objectives, the mission has been further extended until at least the end of 2025.
