Thanks for the replies on this one. I am indeed looking at other tools to open netCDF files. However I just noticed that in qgis 1.4 there is a .nc option (well two actually presumably different formats) when opening a raster image. So I tried it, unfortunately the file opened upside down and possibly a little smaller than it should have done. Has anyone else used this in qgis to confirm the qgis part is working OK so I can go back to the data provider and check the original data itself.

I've used NCO in the past for this,[1] which can average a time dimension in a 3D grid to produce a 2D grid (which can be converted to any other raster format using GDAL). You can do much more with NCO utilities. However, NCO is not user-friendly, since it is command-line work, requires a lot of documentation reading to understand the usage, and is available for almost all operating systems except MS Windows.
