SGP/AERI/C1 - Metadata errors

The latitude, longitude and altitude of the AERI
were incorrectly entered into the ARM database.  The
correct location of the SGP.C1 AERI is:
   Lat: 36.606N
   Lon: 97.485W
   Alt:    316m

SGP/AERI/C1 - Reprocessed: radiance data

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.
