TOMS EP UV Reflectivity Daily and Monthly Zonal Means V008 (TOMSEPL3zref) at GES DISC
Entry ID:
TOMSEPL3zref_008
Summary
Abstract:
This Earth Probe (EP) Total Ozone Mapping Spectrometer (TOMS) version 8 daily zonal means data product contains Lambertian effective surface reflectivity values (Rayleigh corrected). The data are averaged in 5 degree latitude bands. 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.
