Contour (fill or shade) is possible only in 2D region.

Since "temp" is 4 dimensional, you need to fix two dimensions to shade or fill the variable.

Do the following;

shade/l=1/k=1 temp or fill/k=1/l=1 temp

in above cases, temperature values will be contoured for 15-jan-0000 at 1st depth level.

Hope this will help you.

Hai,

Thanks. Now I am going through Ferret tutorial. In that I have seen plotting "coads_climatology"
netcdf dataset. The same way I tried my netcdf data. But I got some error. If possible please give
me your suggestion regarding this. The details I am giving below.

Sudev

Hai,

I am new to Ferret.  I have a netcdf data file. I like to know how can I open and display the variables in this 

file in Ferret. Hope to get your valuable suggestion.
