[gradsusr] If else statement in grads

[Endalkachew Bekele - NOAA Affiliate]

Hello,

Two of your define statements were not enclosed in quotes. See the edited
script below:

'reinit'
'sdfopen d:/Ekman_transport/uwnd.2009.nc'
'sdfopen d:/Ekman_transport/vwnd.2009.nc'
'set lev 1000'
'define W=mag(uwnd,vwnd.2)'
if(W>=3&W<=6);'define cd=(0.29+3.1/W+7.7/W**2)/1000';endif
if(W>=6&W<=26);'define cd=(0.6+0.07*W)';endif
'define taux=1.3*cd*W*uwnd'
'define tauy=1.3*cd*W*vwnd.2'
'd cd'
'printim D:/Ekman_transport/cdrag1.jpg white'

Best,
EB
