I have problems in plotting the 1000 mb geopotential in grads:
set contour gxout
set lev 1000
d geopt
Income commands as stated above and the contours are plotted only on the value 0 and just above the sea.
For grads not draw contours on the value 0?
For grads not draw contours on the continent?
It is because wrf model uses sigma levels?
help!
