Abstract:

The PRISM Climate Group gathers climate observations from a wide range of monitoring networks, applies sophisticated quality control measures, and develops spatial climate datasets to reveal short- and long-term climate patterns. The resulting datasets incorporate a variety of modeling techniques and are available at multiple spatial/temporal resolutions, covering the period from 1895 to the present. Whenever possible, the PRISM Climate Group offers these datasets to the public, either free of charge or for a fee (depending on dataset size/complexity and funding available for the activity). The PRISM "normal" are baseline datasets describing average monthly and annual conditions (precipitation, mean temperature, minimum temperature, maximum temperature, mean dewpoint temperature, minimum vapor pressure deficit, and maximum vapor pressure deficit) over the most recent three full decades. They are the most popular datasets. The current PRISM normals cover the period 1981–2010. The user can select data by the climate variable and by average monthly or annual conditions. The downloadable results are in visual map form and also available as data or metadata files. Long-term average datasets are modeled with PRISM using a digital elevation model (DEM) as the predictor grid. Given their importance, the normals were subjected to extensive peer review. See PRISM datasets page for more information; the data available from this page are "Norm81m" (normals). For information on when the grids were most recently updated, see page having calendar of PRISM data updates.
