Ozone and Atmospheric Chemistry Products

    Operational Products
Global Ozone Monitoring Experiment-2 (GOME-2) GOME-2 is a European instrument flying on the METOP series of satellites. NESDIS products are derived based on the SBUV/2 version 8 algorithm. Currently a total ozone product is operational, which includes aerosol index and reflectivity. Granule products are available as imagery (gif), binary or BUFR, and daily products (1 x 1.25 deg maps) are available in ASCII or GRIB2 format.

Solar Backscatter Ultraviolet Version 2 (SBUV/2) The SBUV/2 is a non-scanning, nadir viewing (field-of-view directly below the satellite track) instrument designed to measure scene radiance in the spectral region from 160 to 400 nm. SBUV/2 data are used to determine total and profile ozone in the atmosphere, and solar spectral irradiance. Products include a 1B Capture product (navigated and calibrated 1B data) in binary format, as well as a Product Master File (PMF) in binary or BUFR.

Total Ozone Analysis from SBUV and TOVS (TOAST) TOAST is a near real-time operational ozone map generated by combining TOVS tropospheric and lower stratospheric (4 to 23 km) ozone retrievals with SBUV/2 spatially smoothed mid-to-upper stratospheric (24 to 54 km) layer ozone retrievals. Products are imagery (png), binary or GRIB format.

Enhanced Total Ozone Analysis from SBUV and CrIS (ETOAST) An algorithm using Total Ozone Analysis of Cross-track Infrared Sounder (CrIS) and Solar Backscatter UltraViolet Version 2 (SBUV/2) has been developed to generate combined UV and IR ozone retrievals. This algorithm is a new version of the current Total Ozone Analysis using Solar Back scatter Ultra Violet (SBUV/2) and Television InfraRed Observation Satellite (TIROS) Operational Version Sounder (TOVS) (TOAST).

GOES Total Ozone Total column ozone is estimated every hour using GOES Sounder data. Estimates are currently limited to cloud-free and partly cloudy regions. Each image is a "pseudo" DPI (Derived Product Image) that is generated outside of the retrieval program by centering a colored square (3x3 field of view box) at the estimate location. Total column ozone is measured in Dobson Units (100 DU = 1 mm of thickness at STP).
