Satellite Instruments
The NASA Earth Radiation Budget Experiment (ERBE) instruments were deployed on multiple satellites. It was first launched aboard the Earth Radiation Budget Satellite (ERBS) in October 5, 1984 by the Space Shuttle, and then again aboard the NOAA 9 satellite on December 12, 1984 and the NOAA 10 satellite on September 17, 1986. The ERBE measurements were collected using two instrument packages (Scanner and NonScanner). The objective of ERBE was to determine the spatial and temporal distribution of the earth radiation budget by directly measuring the broadband outgoing longwave radiation, the broadband reflected shortwave radiation, and the incoming solar radiation over the globe. Spatial coverage of the ERBS satellite was limited to 60N and 60S while NOAA 9 and NOAA 10 had global coverage. The scanner instrument data record contains data from November 1984 to February 1990 with global coverage from February 1985 to April 1989. The current Nonscanner data record extends from November 1984 to September 1999. There are additional 5-year of Nonscanner data from ERBS that have not been released to the public due to instrument issue. These data may be released to the public in the future pending on availability of funding. Intrument coverage: I) Nonscanner Package: Broadband two channels (total and shortwave) Wide Field of View (WFOV) (126 degrees) fixed detectors with view of the entire earth disk at satellite altitude Broadband two channels (total and shortwave) Medium Field of View (MFOV) fixed detectors with ~1000km diameter footprint size at satellite altitude II) Scanner Package: Broadband three channels (total, shortwave, and longwave) Narrow Field of View (NFOV) limb to limb scanning detectors with ~40km diameter footprint size at nidar at satellite altitude
