[gradsusr] prime meridian issue

[Eric Altshuler]

Jonathan,

I used a simple fortran program to subtract 360.0 from each of the first 166 longitudes in your ctl file. The modified ctl file is attached. It should work now.

Best regards,
Eric

Jonathan,

It's strange that the longitudes would be listed in reverse order: 330, 325, 320, ... Could you send your entire ctl file?

Eric

Hello



My WRF model domain straddles the prime meridian: 30 W to 30 E. However, my grads .ctl file prints out the longitude coordinates in the following way



330

325

320

315

.

.

.

5

10

15

.

.

.



When I set LON -30 to 30, only half of the map is filled with data. When I set LON 330 30, I get a message saying my max lon > min lon.



How do I rectify this problem?



Thanks
