Water vapour imagery Measurement Instruments

Measurement Definition: Level-1 product (not a geophysical parameter). Multi-channel imagery covering wavelengths in the range 0.4-14 µm including water vapour bands for atmospheric tracing in clear-air at more levels (e.g., for winds) - Accuracy expressed as Modulation Transfer Function (MTF) at the Nyquist spatial wavelength (twice the resolution). Actually [ MTF-1 ] is used, so that smaller figures correspond to better performance, as usual.

Land Surface Temperature RadiometerApprovedVNIR/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).Multi-purpose imaging Vis/IR radiometer
GEO SARProposedEmergency services: monitoring of landslides, subsidence and ground deformation, seismic and volcanic phenomena, terrain and infrastructure stability, flood mapping. Land: terrain stability, soil moisture and wetlands monitoring. Atmosphere: 2D maps of water vapor concentration with high spatial and temporal resolution.n/a
