Instrument details
Acronym
FPR
Full name
Flat Plate Radiometer
Purpose
Observation of the net radiation flux at the Top-Of-Atmosphere
Short description
Two broad-band channels (solar reflected radiation and total Earth + atmosphere SW and LW radiation)
Background
Precursor of instruments for Earth Radiation Budget from space, flown as a prototype on Explorer 7 in 1959, and until the first NOAA satellite
Scanning Technique
Non-scanning, hemispheric view
Resolution
N/A
Coverage / Cycle
Global, twice daily (LW) or daily (SW) for the ESSA series and NOAA; missing high latitudes for the TIROS series because of the medium-inclination orbit
