Microwave remote sensing(SAR, altimeters, Radiometer and scatterometer) for water resources studies(snow,
soil moisture, water level and river flow).
A precision blackbody(black body) is a controlled source of thermal radiation used to
calibrate infrared radiation thermometers(pyrometers), thermal imagers and radiation heat flux gauges and Radiometers.
Very High Resolution Radiometer(VHRR) with imaging capacity in the visible(0.55-0.75 µm), thred(10.5-12.5 µm) and water vapour(5.7-7.1 µm) channels, provide 2x2 km, 8x8 km and
8x8 km ground resolutions respectively.
Satellite microwave Radiometer(SAMIR) operating at 19 and 22 GHz for study of ocean-state,
water vapour, liquid water content in the atmosphere, etc. The satellite provided ocean and land surface data.
