Re:Where's the raw data? (Score 1)

Because of the larage amount of raw data that is obtained (sats, weather balloons, etc) most of it isn't archived. The post process data can be obtained from the NCEP if you e-mail them. If they charge it is usally only the cost of transferring the data. What might suit your needs better is the NCEP Reanalysis Project. I had downloaded this set a few years ago and it contains data averaged over every four hours on the 2.5x2.5 degree grid and it is free! If you dig around I'm sure it is posted (I met some people a couple of months ago that had just downloaded it). You will have to use a file reading script (free) [like netcdf] to read the data.
