This experimenter-supplied data set was generated by an IBM 360 onto magnetic tapes. It contains earth-located but uncorrected, uncalibrated radiances, housekeeping information, and instrument status. There are four types of data record formats, one for each of the four instrument operation modes: normal step scan, wavelength calibration, scan off/cage cam, and continuous scan. In the normal step scan mode, solar radiation backscattered by the atmosphere is measured by a monochromator in 12 wavelengths that range from 255.5 to 339.8 nm. Simultaneous measurements of the effective UV reflectivity of the surface is obtained by a photometer that operates at 343 nm. In the continuous scan mode, measurements are obtained at 80-ms intervals in the range of 160 to 400 nm in 0.2-nm increments. Both the monochromator and photometer measure between 80 deg N. and 80 deg S., with swath widths of 200 km, separated by 26-deg longitude intervals between successive orbits. Besides the radiances, ancillary data such as snow/ice from the Air Force Global Weather Central, terrain height from the National Oceanic and Atmospheric Administration (NOAA), and cloud information from the Nimbus 7 Temperature Humidity Infrared Radiometer (THIR) are also included in the data set. There are 52 tapes per year.
Transfer of this data set to the Goddard DAAC was completed in February 1996.
