problem with opening NETCDF files

[Pavel Kishcha]

Dear All,

The problem comes about when I am trying to open a NetCDF file in
GRADS version 2.0.a2.

***When I run it by using the command open I see the message:

ga-> open data.ctl
Scanning description file:  data.ctl
Open Error:  Invalid variable record
  --> The invalid description file record is:
  --> nAOT 0 t,y,x
  The data file was not opened.

What am I doing wrong?
Thank you for all of your help.

Cheers,
Pavel


Here is my descriptor file  (data.ctl):
