[gradsusr] Snow depth in GFS files?

[Ivan Toman]

 Hello!

I'm accustomed to use "weasdsfc" variable from GFS to display snow cover
depth (in fact, it's water equivalent). But, it seems that this variable
is now empty - it looks like it does not work anymore after major GFS
upgrade performed on date 2010-07-28. The files I use are
"gfs.t12z.pgrb2bfxx" from
http://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/gfs.xxxxxxxxxx/

Now GrADS gives "Cannot contour grid - all undefined values" if I
display "weasdsfc" variable. Is there any workaround to get snow cover
depth from GFS now?

Thanks in advance,
Ivan
