Solar radiation enters the Earth's atmosphere with a portion being scattered by clouds and aerosols.

What NonScanner products are available?

Even though NOAA-9 and NOAA-10 continued to fly mid to late 1990's, the ERBE Nonscanner record stopped due to instrument failure. Currently only the ERBE/ERBS noncanner data have been reprocessed to correct for satellite altitude drift and other instrument related issues. These new data are only released as the ERBE/ERBS S10N Edition3 product. More information is available in the Edition3 Data Quality Summary, including a special website to obtain user-applied corrected and ASCII formatted data. No S4GN data is available for this latest data. NOAA-9 and NOAA-10 data have not been reprocessed to correct for the satellite altitude drift issue with no plans for a future fix. The satellite altitude drift only affects the Noncanner data set. The scanner data set is not affected by this issue.

Scanner and Nonscanner instruments are processed independently using separated instrument calibration procedure and data processing algorithm. Because of these differences, it is best to work with these two data sets separately.

ERBE/ERBS Nonscanner operated for ~20 years November 1984 - August     2005
ERBE/ERBS S10N Ed3 Nonscanner operated for ~14 years January     1985 - September 1999
ERBE/NOAA-9 Nonscanner operated for ~8 years February    1985 - November 1992
ERBE/NOAA-10 Nonscanner operated for ~8 years February    1985 - November 1992

** Note** : ERBE/ERBS nonscanner TOA flux data from October 1999 to August 2005 is unavailable to the public due to unresolved instrument anomaly issues.
