Measurements and Applications
VNIR/SWIR/TIR radiometer with three independent focal planes fed by a single telescope to acquire images of all land and coastal areas with high radiometric accuracy and spatial resolution. Acquistion are during day and night in TIR bands and during day in VNIR/SWIR bands.
Monitoring evapotranspiration (ET) rate at European field scale by capturing the variability of Land Surface Temperature (LST) (and hence ET) enabling more robust estimates of field-scale water productivity. Supporting a range of additional services benefitting from TIR observations (e.g. soil composition, coastal zone management, High-Temperature Events (HTE), urban heat islands).
