Time Series Values for Individual Locations



This section provides an interactive tool for analyzing time-series data for a single location. For larger areas, use one of the other tabs to retrieve the gridded data, or use one of our bulk download mechanisms.

The grid cells analyzed are the standard PRISM 4km, except the 30-year normals which are also available at 800m resolution. Choose a location by navigating the map or specify lat/lon coordinates to zoom to that location. The highlighted box denotes the enclosing PRISM grid cell. Adjust the settings as desired, then press the Retrieve button to display the time series and make the data available for download.

Note: Rather than calculating days based on the 24-hour period ending at midnight local time, PRISM defines a "day" as the 24 hours ending at 12:00 Greenwich Mean Time (GMT, or 7:00am Eastern Standard Time). This means that PRISM data for May 26, for example, actually refers to the 24 hours ending at 7:00am EST on May 26.

When the Interpolate option has been selected, the user may click on any location (not necessarily aligned with PRISM grid cells) and the values from surrounding grid cell centers will be factored in using inverse-distance squared weighting.

Data stability indicates how likely the data is to change in the future. Results that include dates older than 6 months are considered stable because they are unlikely to change until a major new release of PRISM. If they include dates that are 1-6 months old they are considered provisional, since they are likely to change as our reporting networks finalize their information. If any dates fall within the current month, users are cautioned to treat them as early results; this data is certain to change as new reporting stations are added and quality control measures are applied. The calculations use as many as possible of the station networks and data sources ingested by the PRISM Group, not just those that have existed for long periods of time. See PRISM datasets for more information; the data available from this page are from the latest versions of "Norm" (normals), and "AN" (daily and monthly). For information on when the grids were most recently updated, see calendar of PRISM data updates.

Notes: Clear sky irradiance and cloud transmittance are available as monthly normals only. VPD and solar variables are available in metric units only.
