[RegCNET] About the GrADS XDEF

[Mohamad Ibrahim OMAR]

Dear Lang Wang
the iy and jx dimension in RegCM-4.1.1 are in Kilometers not in degree east and degree north as the Grads can recognize as lat and lon so you can use the exe file GrADSPlot in Bin folder to plot the RegCM-4.1.1 output or you can use the NCL to plot the data
thanks

Subject: [RegCNET] About the GrADSXDEF
 

Dear RegCM4.1 users
 
I am running the test of the RegCM4.1. When I got the result named "test_001_ATM.1990060100.nc "and tried to xdfopen it by GrADS. The GrADS can't xdfopen it reporting "SDF file has no discernable X coordinate", when I wrote in the *.CTL with "XDEF  62 linear  -1830  60". The "ncdump program" of the file is showed as follows.
 
I guess it is deduced by the start num of "-1830". How to solve this problem?
 
Thank you so much in advance!
 
Best regards
 
Lang Wang
