Dear group users,
I am rather new to IDL and completely new to the GRIB data format. I
have tried to figure out how to read GRIB data into IDL and have found
several packages on the web, seemingly all based on the rather old
wgrib c programme. The latest package I found at ITTs webpage by Andy
Pursch (http://www.ittvis.com/codebank/search.asp?FID=488),
and it was
easy to install and seems to be running fine. My problem, however, is
that the documentation is quite poor and I cannot understand the
obejct structure created. For example, I cannot see how to identify
which parameter is in each "record", or what time of day it
represents. Also, I work with ECMWF data which apparently use
different parameter codes than the official WMO. Can anybody help with
some good advice on how to advance?
Yours sincerly,
Sara.
