Description:
On June 10th, staff from the University of Wisconsin-Madison visited the SGP CART site to 
upgrade the software running on the AERI instrument.  While there, they took the 
opportunity to perform some routine checks of the instrument.  Due to these tests, data from 
6/10/97 - 6/11/97 should not be ingested or used for scientific studies.
The software installed was the same software as will be used on the next generation AERIs 
(AERI-Nexts).  The AERI-Nexts have some improved hardware capabilities, which is taken 
advantage of by the new software.  Unfortunately, as the AERI 01 at the CART site does not 
have these capabilities, NaNs resulted in a couple of fields in the sgpaeri01summaryC1.a1 
platform.  These NaNs are placeholders in arrays that were too long for the AERI01 but 
the correct length for the AERI-Nexts.  All valid data (non-NaN data) is correct, and 
hence these NaNs should be ignored.  A routine was modified on 6/24 which effectively fixes 
the problem (the size of the arrays written out is now determined by the hardware's 
capabilities, versus outputting a fixed length vector).

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.
