Im sure this is probably boring old news to most of you...but at the risk of being redundant I thought I would share just incase.
Ncview is a quick and easy way of viewing netcdf formatted files. No code required just a click of a button. Ncview typically needs to be run in a linux based environment (mac os x works nicely too). It can open up several data files at once and will run a little movie of all your data if you so fancy. It also has a range of different colour bars you can choose from.
