I hope this gives you a few things to get started upon. As you might have guessed this is probably not something I want to waste much time on. Almost all the funding for the work on developing these datasets has come from the US Dept of Energy. They are happy with me not passing on the station data, as we make the gridded products, which are much easier to use. Also the raw station data have been modified by use, and we don’t still have the original data (as received, or as digitized by us in the 1980s).
