I've been squirreling data away, and posting here, even before the current threats to US Science. But a post by Tamino prompted me to get a wriggle on. In particular, I decided to systematically post the files of monthly data that I use for graphs and tables on the latest temperature page. They are tables looking like this, but going back to 1850. My idea is to update weekly, and store monthly versions, so one can refer back. I have started doing that; there is a CSV file and a R data format file, with a readme, zipped. The URL for this month is
and it will change in the obvious way for future months. I'll probably put a table of links on the portals page, once a few have accumulated.
I'll look for other opportunities to back up. I'm actually more dependent on current data like GHCN, ERSST and AVHRR data, and the reanalysis. I'm more optimistic there, because that data is collected for weather forecasting, which has powerful clients. So while access may be bumpy, I don't think it will be lost.
