Description

The Solar Backscattered Ultraviolet (SBUV) from Nimbus-4 Level-2 daily product (BUVN04L2) contains ozone nadir profile and total column data from retrievals generated from the v8.7 SBUV algorithm. The v8.7 SBUV algorithm estimates the ozone nadir profile and total column from SBUV measurements using 1) the Brion-Daumont-Malicet ozone cross sections, 2) an OMI-derived cloud-height climatology, 3) a revised a priori ozone climatology, and 4) inter-instrument calibration based on comparisons with no local time difference.

The BUVN04L2 product is written as daily files using the netCDF-4 format, with file sizes ranging from about 1 to 5 Mbytes. Data are available from May 1970 through April 1976. The previous v8.6 SBUV algorithm data were available as part of the 2006 MEaSUREs "Creating a Long-Term Multi-Sensor Ozone Data Record" project.
