Earth Radiation Budget Experiment (ERBE) measurements were collected from three satellites (ERBS, NOAA-9, NOAA-10) carrying two ERBE instrument packages (Scanner and NonScanner). The objective was to measure global albedo, fluxes, and solar incidence. The ERBE instruments on board the NOAA-9 and NOAA-10 satellites provide global spatial coverage, while the scanner instruments on board the ERBS provides coverage between 67.5 degrees north and south latitude and the nonscanner instruments on board the ERBS provide coverage between 60 degrees north and south latitude. Because ERBS is in a precessing (57-degree) orbit, the ERBE instruments on board this satellite provide diurnal sampling.
ERBS, a dedicated NASA satellite, was launched in October 1984. The NOAA-9 and NOAA-10 satellites, both operational weather satellites maintained by NOAA, were launched in December 1984 and September 1986, respectively.
