[gradsusr] writing results & variables to a text file

[Rowell, Mason D.]

Wesley,

Will command syntax like this work for wgrib as well (not wgrib2)? I have had instances of just wanting to extract one variable at one exact location but the wgrib documentation didn't have examples of how to do this (what options to use after wgrib) for a specific location.

Alireza,

   "If all you have is a hammer, everything looks like a nail."

    Before trying to find a GrADS solution, consider whether GrADS is
the right tool.


(A)  To find Washington DCs T2m for a single file, 1.grb2

    wgrib2 1.txt -match ":TMP:" -match ":2 m above ground:"  -s -lon -53
38 >1.txt


(B) Do the same for *.grb2 (only works for v0.1.9.3  5/2011 or later)

    cat  *.grb2 | wgrib2 - -match ":TMP:" -match ":2 m above ground:"
-s -lon -53 38 >all.txt


    for older wgrib2:  cat *.grb2 >tmp.grb2
                                  wgrib2 tmp.grb2 -match ":TMP:" -match
":2 m above ground:"  -s -lon -53 38 >all.txt
