These are monitored by Polar orbiters (NOAA) and geostationary (GOES) satellites. Visual and infrared channels on these satellites allow type, coverage, and thickness of clouds to be determined. ... upwelling. Sea Surface Temperatures These are measured by the Advanced Very High Resolution Radiometer (AVHRR) on NOAA polar orbiters. They determine temperatures by sensing infrared radiation coming from ...
