Hello,
Can anyone tell me why gddiag needs a 'TMPK' grid to calculate the
vertical wind shear of a layer?
TMPK is used in computation of THTA for the layer to arrive at DZ
in pressure coordinates. see equation used in:

GDFILE = wind.grd
GDOUTF = wind.grd
GFUNC = wshr(wnd)
GDATTIM = 990101/0000
GLEVEL = 200:850
GVCORD = PRES
GRDNAM = wshr
GPACK =
GDDIAG > r
[DG -7] Input grid TMPK ^990101/0000 @200 %PRES in WSHR cannot be
found.
The grid file contains U and V winds at 200 and 850 mb. Thanks.
Chris
