The Solar Backscattered Ultraviolet (SBUV) from Nimbus-7 Level-2 daily product (SBUVN07L2) contains ozone nadir profile and total column data from retrievals generated from the v8.6 SBUV algorithm. The v8.6 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 SBUVN07L2 product is written as daily files using the HDF5 format, with file sizes ranging from about 1 to 5 Mbytes. Data are available from November 1978 through May 1990. The SBUVN07L2 data product was used as input in creating the SBUVN07L3zm monthly zonal mean data product.
