TOMS Earth Probe UV-B Erythemal Local Noon Irradiance Monthly L3 Global 1 deg x 1.25 deg Lat/Lon Grid V008 (TOMSEPL3mery) at GES DISC
Entry ID: TOMSEPL3mery_008


Summary
Abstract: This Earth Probe (EP) Total Ozone Mapping Spectrometer (TOMS) version 8 monthly averaged 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
Use Constraints Earth Probe TOMS data since 2002 should NOT be used for trend analysis because of calibration problems.
