Historical Model Data Files

If you only need historical data periodically, our basic historical data only subscription may fulfill your needs. All of the site specific and composite data files on this page are updated once per month, usually on or around the 7th. Hourly and daily data has undergone extensive cleaning and filling procedures. Most sites are free of missing data, and most errors have been corrected. Historical data is updated with the quality controlled data from NCDC each month, and then with the final edited versions of the data (where available) a few months later. If you notice any questionable or erroneous data, please contact us.

Historical Model Forecast Average U.S. Population Weighted Temperature Anomalies
