Re: NCL webpage problem

Dear Mary!

Thank you very much for reply.
The file has lat lon coordinates in the form lat(j,i), lon(j,i).
Following is the header information of data file. Please advise in the
light of this information.

Thanking you in anticipation!

P.S: problem of NCL page loading is solved. Thanks again.
