Abstract: The Solar Backscattered Ultra Violet (SBUV) from NOAA-11 Level-2 daily product (SBUV2N11L2) 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 SBUV2N11L2 product is written as daily files using the HDF5 format, with file sizes ranging from about 1 to 5 Mbytes. Data are available from January 1989 through March 2001. The SBUV2N11L2 data product was used as input in creating the SBUV2N11L3zm monthly zonal mean data product.
