TOMS Earth Probe UV-B Erythemal Local Noon Irradiance Daily L3 Global 1 deg x 1.25 deg Lat/Lon Grid V008 (TOMSEPL3dery) at GES DISC
This Earth Probe (EP) Total Ozone Mapping Spectrometer (TOMS) version 8 daily global gridded data product contains UV-B erythemal local noon irradiance values. 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).

- 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
