The data are mapped to a global grid of size 180 x 288 with a lat-long resolution of 1.00 x 1.25 degrees. These data are stored in an ASCII format.
The TOMS data were produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center (Code 614).

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 analysisTOMSgov.nasa.esdis.umm.instrumentshortnameTotal Ozone Mapping SpectrometerNot providedTOMSgov.nasa.esdis.umm.projectshortnameTotal Ozone Mapping SpectrometerEP-TOMSgov.nasa.esdis.umm.platformshortnameEarth Probe-TOMSEarth Observation Satellites
