Welcome to the North American Seasonal Precipitation Atlas. This web application provides access to cool- and warm-season reconstructions of total precipitation and the standardized precipitation index on a 0.5° latitude/longitude grid centered over North America from AD 0000-2016.
Maps and time series can be created using tools under the "Maps" and "Time Series" menus, respectively. For details on how to create maps and time series, see the "Help" menu. An animation that runs through each year of the reconstruction from AD 0000-2016 is available via the web application.
Questions, comments, or suggestions may be sent to Dorian J. Burnette.
The entire dataset can be downloaded from NOAA Paleoclimatology.
