[gradsusr] How to handle Ensemble using sdfopen

[Lee Byerle]

Hi, Howard,

The command:

'set e 1'

should work...

Here is a sample I use:

'sdfopen http://nomads.ncep.noaa.gov:9090/dods/gens/gens20140603/gep_all_00z'

'set lon 180 360'
'set lat 22 90'
'set lev 500'


'set e 1'
'set grads off'
'set cmark 0'
'set clevs 5640'
'set clab off'
'd hgtprs'
e=2
cols='2 3 4 5 6 8 9 10 11 12 13 14 2 3 4 5 6  8 9 10 11 12 13 14 2 3 4 5 6 7 8 9 10 11 12 13 14 '
while (e<=21)
 'set e 'e
 c=subwrd(cols,e)
 'set ccolor 'c
 'set cmark 0'
 'set clab off'
 'set clevs 5640'
 'd hgtprs'
 e=e+1
endwhile

Hope this helps,
Lee
