hi there,
I am using IDV 5.0u2 and 5.1u2 try to read GrADs binary grid files through
control file (CTL File).
The Ctl looks like this and it works fine using Grads to open it.
both 5.0 and 5.1 can open ctl file fine and plot fine.
only issue remain is the time dimension
no matter how I change the tdef line, "12z20MAY2015"
it always show starting from 1970-01-01-08 CST in IDV
in this case:
1970-01-01-08 CST
1970-01-01-09 CST
1970-01-01-10 CST...
If I change "60mn" to "1dy", it will appear like
1970-01-01-08 CST
1970-01-02-08 CST
1970-01-03-08 CST...
If I change "49", IDV will report error.
Seems to me that the IDV does not get any infomation from "12z20MAY2015" in the
line TDEF in CTL file.
If anyone has any experience please do not hestitate to share with me. Many
thanks.
