Historical Soil Temperature data?

August 25, 2015 8:22 AM

I'm interested in looking at historical soil temperature data for the DC area - I have found lots of forecasts online as to what the soil temperature will look like in the next few days, but I haven't found any as to what the temperature looked like historically. In particular, I would be interested in looking at what the soil temperature was in any given day or week in the past few years. An added bonus would be some sort of general summary similar to weather summaries that say "in January in DC, temperatures average x-y degrees"

It looks like you want NOAA dataset "U.S. Soil Temperatures (DSI-9639)" for 1967 through 1981 temps, and "DSI-3200 Cooperative Summary of the Day (C00314)" for post-1981 temps. I don't believe these are available in an interactive online format, but for both data sets, you can contact NCDC customer service via the contact info at the bottom of both linked pages.
