[needdata] grib2 radar data

[Steven Babin]

I have decoded some radar echo data from GRIB2 to ascii, but I don't 
have any English language documentation on how the radar echo data are 
put into the file.
I now need to know how to determine the latitude, longitude and dBz (or 
dBm) of the data from the ascii numbers.  Can anyone provide me with some
documentation or a radar template/table file for interpreting my ascii 
file of echo data?

Thanks for your help,

Steve
