Global Ozone Monitoring Experiment 2 (GOME-2) Products

The GOME-2 instrument was designed by the European Space Agency to measure atmospheric ozone, trace gases and ultraviolet radiation. It is a scanning instrument (scan width 1920 km) with near global coverage daily. The field-of-view on the ground is 80 km X 40 km.

NESDIS is developing GOME-2 atmospheric chemistry products. The total ozone product, based on the SBUV/2 Version 8 algorithm, is now operational. It is available in binary and BUFR formats. The algorithm also produces aerosol index and reflectivity values, which are included in the total ozone binary product.

For users only interested in the total ozone field, we produce a daily gridded total ozone product (1x1.25 degree grid) in ASCII and GRIB2 format. We also extract the Magnesium II index (MgII) information into a daily ASCII file for our solar and space users.

GOME-2 1B granules (raw data), total ozone binary files, gridded ASCII files and MgII index files are currently archived at CLASS.
