  1. Satellite Two types: Polar Orbiting very high resolution only twice a day Geostationary lower resolution nearly continuous 3 basic channels VIS (visible) IR (infrared) WV (H2O) www.arl.noaa.gov/ready/cmet.html#modelgraphics Radar Surface based uses microwave energy sent in rapid pulses to detect wind & precip Network across USA WSR88D located at 125 sites including Alaska, Hawaii, Guam and PR Displays returns of precip & wind in a 250 mile radius of site refreshed every 6 min.
