Measurements and Applications
|
Measurements of land and sea surface temperature, cloud cover, snow and ice cover, soil moisture and vegetation indices. Data also used for volcanic eruption monitoring. Multi-purpose imagery. 4-channel radiometer covering VIS, NIR, MWIR and TIR, respectively. Digitised version of VHRR (Very High Resolution Radiometer) previously flown on NOAA 2 to 5; 4 channels instead of 2.
