Earth Radiation Budget (ERB) instrument consists of three separate
elements with a total of 22 sensors: a ten channel solar telescope, 4
fixed wide field of view (WFOV) sensors that view the entire visible
disk of the Earth, and an 8 channel (4 telescopes, 2 spectral windows,
0.2 - 4.8 microns and 4.5 - 50 microns) narrow field of view (NFOV)
The Master Archival Tape (MAT) contains ... calibrated, earth-located
radiances/irradiances and raw digital counts for all of 22 ERB
channels. It also contains other housekeeping data, such as
instrument temperature, satellite ephemeris, and attitude data. The
NFOV scanner failed on June 22, 1980 and its data is available only
for the period November 1978 through June 1980.
The MAT contains 3 day's worth of data and is the primary source for
the generation of Level-II and III ERB data products.
