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 Using S-NPP/OMPS LP and S-NPP/CrIS (LTOAST) This algorithm is a new generation of the current operational TOAST. It replaces data from the sensors used to compose the TOAST (SBUV/2 and HIRS) with the most newly developed sensors: OMPS LP (S-NPP) and CrIS (S-NPP). This leads to improved product accuracy and provides continuity of TOAST contributions to the ozone researchers and other users.

Total Ozone Analysis Using NOAA20/OMPS and NOAA-20/CrIS (NTOASTJ1) This algorithm is a new generation of the current operational TOAST. It replaces data from the sensors used to compose the TOAST (SBUV/2 and HIRS) with the most newly developed sensors: OMPS NP (NOAA-20) and CrIS (NOAA-20). This leads to improved product accuracy and provides continuity of TOAST contributions to the ozone researchers and other users.

Ozone Mapping Profiler Suite (OMPS) OMPS measures the global distribution of the total atmospheric ozone column on a daily basis. It also measures the vertical distribution of ozone from about 15 km to 60 km, though somewhat less frequently. Ozone is an important molecule in the atmosphere

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).
