Historic precipitation in Alaska for 1901-2015, with regional subsetting by SASAP region

The purpose of this project is to extract historic average Alaskan precipitation across different time intervals for periods of interest (e.g. spawning season, growing season, monthly averages) across different regions of Alaska. Details on the extraction can be found in the file "PrecipitationHistoric.ipynb" within this package. In particular, the data files in this package comprise records for regional and temporal subsets of the original dataset, with the regional divisions determined by the SASAP project. These data were derived from the "Historical Monthly Precipitation - 1 km CRU TS" dataset, available at http://ckan.snap.uaf.edu/dataset/historical-monthly-precipitation-1-km-cru-ts. The "Historical Monthly Precipitation - 1 km CRU TS" dataset was created by Matthew Leonawicz, Michael Lindgren, Tom Kurkowski ([e-mail]), Scott Rupp, and John Walsh, and was funded by the Arctic Landscape Conservation Cooperative, Western Alaska Landscape Conservation Cooperative, and Northwest Boreal Landscape Conservation Cooperative (LCCs) and the Alaska Climate Science Center.
