| Description: | Due to a software error in the real-time calibration software, the AERI-01 radiance data
between 10/96 and 6/97 were incorrectly calibrated. All of the AERI-01 radiance data
collected at the SGP central facility during this time period was corrupted by this software
error and were reprocessed to correct the radiance data. The error also affected all
derived products of the AERI radiance data. AERI data collected prior to and after this time
period was unaffected by this programming error.
The proper calibrated radiance spectra was recovered from the raw archived dataset through
post-processing. This reprocessing of the AERI data was carried out by the instrument
mentor at PNNL and confirmed independently by Univ. of Wisconsin. The reprocessed AERI
radiance data during the period 10/96 to 6/97 supercedes all previous versions of the AERI
data in all instances.
