TOMS Earth-Probe Ozone (O3) Total Column 1-Orbit L2 Swath 50 x 50 km V008 (TOMSEPL2) at GES DISC

Version 008 eng
  • Abstract
    The Earth Probe (EP) Total Ozone Mapping Spectrometer (TOMS) version 8 orbital swath data product contains total column ozone, UV aerosol index, and Lambertian effective surface reflectivity (Rayleigh corrected) at approximately 50x50 km2 resolution (at nadir). This product also contains some auxiliary derived and ancillary parameters including N-values, SO2 index, cloud fraction, cloud pressure, ozone below clouds, terrain height, geolocation, solar and satellite viewing angles, and data quality flags. These data are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5). The TOMS data were produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center (Code 614).

    Quality
    EP TOMS started experiencing calibration problems since 2002. For data beginning in year 2000, the calibration has been stabilized relative to NOAA-16 SBUV/2 in the equatorial zone. Because of continuing changes in the optical properties of the front scan mirror that are not well understood, data are showing a latitude dependent error that cannot be corrected by a simple calibration correction. The calibration appears to be stable near the equator. But by 50 degrees latitude, there is now a -2% to -4% error in TOMS, a bit larger in the northern hemisphere than in the southern hemisphere. Because of this error, data since 2002 should NOT be used for trend analysis.
