Hi Phil,
Thanks for your reply. I guess I assumed that if the file was intended to
be read as ASCII, that it would already have its header record. My bad; I
can easily enough add the required info. Then do I just rename it .asc?
As for the extraction/decompression software - that wasn't a problem at all.
I just didn't know what to do with the file once I had it.
Thanks again,
Cathy

The structure of these files seems to be laid out clearly in the README
file:
http://climate.geog.udel.edu/~climate/html_pages/README.ghcn_clim2.html
They are just XY coordinates followed by a series of measurements at
these locations for different time points. You should be able to read
these into your favorite GIS as ASCII data. Of course you'd want to add
a header record and replace 1+ spaces with single commas to make the
import easier since they appear to be constant width fields.
By the way, WinZip and gzip.exe handle the .Z compression format easily
on a PC.
