The data files in this directory have been compressed and should be
transferred as binary files. 

The data are contained in the following files. The numbers following
the file description refer to the file sizes (in mbytes) in uncompressed
and compressed forms, respectively.

Fields of geopotential height (z), zonal wind (u), meridional wind (v), 
temperature (T) and specific humidity (q) were objectively analyzed 
using multiquadric interpolation (Nuss and Titley 1994) over the Large 
Scale Array (LSA) of TOGA/COARE at 25 mb resolution from 1000 to 25 mb 
and at 1 degree resolution in both the latitude and longitude directions.  
Surface fields and surface pressure was also analyzed over the LSA. 
This analyses was done for 480 six hour intervals (00, 06, 12, and 18UTC) 
during the COARE Intensive Observing Period (IOP - 1 November, 1992 
through 28 February, 1993). The missing value flag is -999.0 for all fields. 

To read data, first untar files that you want, then uncompress these files
using the UNIX uncompress command. Fortran program "readascii_grids.f" has 
been supplied to help users read the various data fields. One should refer to
this program for information on the convention used is creating the data files.
