Description
The PRISM daily and monthly datasets are gridded climate datasets for the conterminous United States, produced by the PRISM Climate Group at Oregon State University.
Grids are developed using PRISM (Parameter-elevation Regressions on Independent Slopes Model). PRISM interpolation routines simulate how weather and climate vary with elevation, and account for coastal effects, temperature inversions, and terrain barriers that can cause rain shadows. Station data are assimilated from many networks across the country. For more information, see the Descriptions of PRISM Spatial Climate Datasets.
Note
- Warning: This dataset should not be used to calculate century-long climate trends due to non-climatic variations from to station equipment and location changes, openings and closings, varying observation times, and the use of relatively short-term networks. Please see the dataset documentation for more details.
- The assets have start time of noon UTC, not midnight UTC.
- It takes time for observation networks to conduct quality control and release station data. Therefore, PRISM datasets are re-modeled several times until six months have elapsed, when they are considered permanent. A release schedule is available.
- For use of the 30 arc-second (~800 m) version of this dataset please contact the provider at prism-questions@nacse.org
