NSA/AERI/C1 - Data file header manipulated

The NSA.C1 AERI data for 19990321 and 19990324 were processed on
July 23, 2004 using version 1.24 of the ingest.  This resulted
in the creation of .b1 level data files.  Because the other March
1999 data are .a1 level data files, the .b1 files were modified
using nc_tools (nc_copy, ncvarrename, ncattcopy) to create .a1
level data files.

The data in the files were not changed in anyway.  Only header
modifications were made.  The user may notice small header differences
between these files and others from March 1999.
