[gradsusr] How to solve the problem for Julian date for grads.

[Jennifer M Adams]

This error means that the file size is wrong. Based on your descriptor file, the file should be 9000 x 3000 x 4 bytes. 

I did not download, but if 54000000 is the file size, it is too small by a factor of 4. 
>>  rgccs1h1618413.bin (54000000)

>> I think the problem is that you have an extra character (a double quote: “) at the end of your filename in your DSET entry. Here is a helpful debugging feature: After you open the descriptor file, invoke the command ‘set misswarn on 1’ (assuming this is file #1) and then try to display some data. If GrADS is unable to find the data file, it will tell you the name of the file it is looking for.
