To extract data from the databases in the "Normal Water Temperature
and Ice Cover of the Laurentian Great Lakes: A Computer Animation,
Data Base, and Analysis Tool", use one or both of the enclosed programs.

1) To read the grid point locations, bathymetry data, water temperature
   data, or the ice cover data, use the program RDTMPICE.  It will
   prompt you for the lake name, start month, end month, and data type
   selection.  It will then produce an ASCII data file for your use
   called DATAOUT.xxx where xxx = SUP, MIC, HUR, ERI, or ONT.

   The output file can be quite large, especially if you output the
   temperature and/or ice cover data.  For example, to extract all of
   the data for all months for Lake Erie, the data file will be
   16,927,932 bytes.

2) To read the vertical temperature profile data, use the program READPROF.
   This program is implemented from the command line as follows :
     READPROF XXX           where XXX = SUP, MIC, HUR, ERI, or ONT.  
   It will produce an ASCII data file called ASC_PROF.XXX which contains 
   temperature profiles for the entire year.

   The output file can be quite large depending on the lake, so there is an 
   option of producing only one month's worth of profiles.  The option is 
   implemented at the command line and the syntax is as follows :
   READPROF XXX MMM      where MMM = (1, 2, .. 12) -or- (JAN, FEB, ... DEC)
