 Discussion of Problem:

The AERI Profile QME (Wayne Feltz) first detected a problem with AERI-01 data
from the SGP CF.  Investigation by site personnel on June 14, found numerous
bird droppings in the area around the AERI-01 sky hatch plus some grass lying
across a portion of the hatch opening.  Using the AERI-LBLRTM QME to analyse
the data after the fact it appears likely that nesting birds placed pieces of
grass in a position to obstruct the AERI field of view to the sky.  By some
quirk of fate, the problem actually fixed itself about 12 hours before the
site personnel made their inspection of the AERI viewport and discovered the
evidence described above. The system has been operating normally since June
13, 1996 22:00 UTC as confirmed by a recent analysis of the AERI-LBLRTM QME
results.


Other observations/measurements impacted by this problem:

This effects all QMEs and other analyses that use the AERI-01 data.


Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)

It is unlikely that this data can or will be corrected.

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.
