- Cort Willmott & Kenji Matsuura of the University of Delaware have put data together from a large number of stations, both from the GHCN2 (Global Historical Climate Network) and, more extensively, from the archive of Legates & Willmott. More details can be found here for temperature and here for precipitation. The result is a monthly climatology of precipitation and air temperature, both at the surface, and a time series, spanning 1900 to 2010, of monthly mean surface air temperatures, and monthly total precipitation. It is land-only in coverage, and complements the ICOADS (International Comprehensive Ocean-Atmosphere Data Set) data set well. For a complete description of the data as given by the providers, related datasets and references to relevant papers please see their web pages at the University of Delaware.

- Please note: If you acquire UDel_AirT_Precip data products from PSD, we ask that you acknowledge us in your use of the data. This may be done by including text such as UDel_AirT_Precip data provided by the NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at http://www.esrl.noaa.gov/psd/ in any documents or publications using these data. We would also appreciate receiving a copy of the relevant publications. This will help PSD to justify keeping the UDel_AirT_Precip data set freely available online in the future. Thank you!
