Jonathan,

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

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
