BUV/Nimbus-4 Level 1 Radiance and Housekeeping Data in Telemetry Units V001 (BUVN4L1PDB) at GES DISC

The Nimbus-4 BUV Level-1 Radiance and Housekeeping Data in Telemetry Units collection contains the raw counts measured by the Backscatter Ultraviolet Spectrometer every 32 seconds at 12 wavelengths between 250 and 340 nm during the daylit orbit portion. The data collection also contains ephemeris data, experiment subsystem status information, and spacecraft housekeeping and orbit data. This data collection was used to create the Level 1 Radiance U-Tape or RUT product.

The data were originally created on IBM 360 machines and archived on magnetic tapes. The data have been restored from the tapes and are now archived on disk in their original IBM binary file format. Each file contains about one orbit of data. The data files consist of 850 2-byte word records which are blocked in up to ten records. The first record in the file is the header record, followed by a series of data records, and ends with a trailer record. A typical orbit file is about 260 kB in size.

The BUV instrument was operational from April 10, 1970 until May 6, 1977. In July 1972 the Nimbus-4 solar power array partially failed such that BUV operations were curtailed. Thus data collected in the later years was increasingly sparse, particularly in the equatorial region.

This product was previously available from the NSSDC with the identifier ESAC-00024 (old ID 70-025A-05E).
