ncview

ncview is not recommended for quality graphical displays, but is a very handy tool for a quick first-look at the data.

ncview is freeware (http://meteora.ucsd.edu/~pierce/ncview_home_page.html) that can be used to view data in 's' files.

ncview only displays data as is; with the exception of country and U.S. state borders, if history is written to one file per history time.

 

Below is a sample plot of what you can see with this utility (this image depicts SNOALB in the default WRF domain).
