Hi,
I just wanted to expand a little on Brian's note.
What I found is that GRDDISP/GRDCOPY do not correctly pick out both
components of 10 meter winds. The 10 meter U component does correctly
get chosen, but the 10 mb V wind is used with the 10 m U componet to
create WINDB. A GRDLIST from a dataset that contains both 10 m and 10 mb
winds shows what is going on:
GRDLIST MYDATA/GRIDS.6010 TIME=0 FHOUR=15 PAR=WINDB LEV=10[M] NUM=ALL
Dataset position 6010 Directory Title=
PAR LEVEL DAY TIME SRC FHOUR FDAY FTIME GRID PRO
---- --------- ------------ -------- ---- ----- ------------ -------- ----- ----
U 10 M 26 NOV 02330 00:00:00 AVN 15 26 NOV 02330 15:00:00 293 MERC
V 10 MB 26 NOV 02330 00:00:00 AVN 15 26 NOV 02330 15:00:00 200 MERC
Number of grids listed = 2
GRDLIST - done
The workaround that I sent Brian was to use two invocations
of GRDCOPY to copy each individual component to a scratch GRID file
and then run GRDDISP using it. Individual GRDCOPYs work fine:
DSSERVE ADD G/G GRID 1 9999 TYPE=GRID "ALL LOCAL GRID FILES
Adding the group G as a local dataset
Group/Descriptor Type Format & Range RT Comment
------------------------ ----- ------------------ -- --------------------
G/G GRID GRID 1-9999 ALL LOCAL GRID FILES
DSSERVE: done
GRDCOPY MYDATA/GRIDS.6010 G/G.1 PAR=U LEV=10[M]
Total grids copied=1
GRDCOPY - done
GRDCOPY MYDATA/GRIDS.6010 G/G.1 PAR=V LEV=10[M]
Total grids copied=1
GRDCOPY - done
GRDLIST G/G.1 NUM=ALL

---- --------- ------------ -------- ---- ----- ------------ -------- ----- ----
U 10 M 26 NOV 02330 00:00:00 AVN 15 26 NOV 02330 15:00:00 1 MERC
V 10 M 26 NOV 02330 00:00:00 AVN 15 26 NOV 02330 15:00:00 2 MERC
Number of grids listed = 2
GRDLIST - done
GRDDISP G/G.1 PAR=WINDB LEV=10[M] NAV=C PINT=2
GRDDISP: Done with graphic frame 11
So, there is a problem with GRDDISP that needs to be attended to.
