Climate Estimates and Plant-Climate Relationships
Get Climate-FVS Ready Data


Climate-FVS is a modification to the Forest Vegetation Simulator, a stand dynamics model generally used to support forest planning, project analysis, and silvicultural prescription preparation.

Climate-FVS reads an input a data file created from using this web page. The file includes derived variables like those available from the Custom Climate Data Request page plus relevant species-climate profile scores described on the Species-Climate Profiles page. The data for all GCM and SRES scenarios and for all time slices that are available are included automatically. Users select which ones to use in Climate-FVS projections in that software, not here.

NOTE: These data are only available for Western United States (excluding Alaska, longitude -125 to -102 and latitude 31 to 51 degrees).

How it Works

  1. You prepare a file of locations for which Climate-FVS-ready data are produced. Normally, each location represents one stand, or "setting".
    1. Do not include a header record. The data must start in the first line.
    2. The data file has four columns coded as space separated values (commas also work): PointID, Longitude, Latitude, and Elevation. Please note that longitude is listed before latitude.
    3. Longitude and latitude are in decimal degrees. Longitudes in North America have a negative sign and are shown as degrees west of 0. Elevation is in meters.
    4. Generally the specified values represent the center of the stand polygon.
    5. If a PointID includes blank(s), enclose it in quotation marks.
    6. PointIDs should be unique, if they are not, they will be changed to make them unique.
    7. The file extension is normally .txt. If you desire you may compress your file so that the extension is .zip (implies a zip file) or .gz (implies a gzip file). Only one file may be contained in the compressed file.
    8. An example record is shown below for a location in Moscow, ID where the longitude is -117.0 degrees, the latitude is 46.73 degrees, and the elevation is 787.3 meters:

    9. "Moscow ID" -117.0 46.73 787.3

  2. You specify an Email address we can use to contact you.
  3. You specify the data file to send our site.
  4. Our server processes the request and builds a zip file of the output data.
  5. Our server sends you an Email with links included that you can use to retrieve the data you requested. You are given 48 hours to recover your data from the time the Email message is sent. Short runs take 5 to 10 mins, long runs can take an hour or two.
  6. Once you get the file, copy the file named FVSClimAttrs.csv to the FVS data directory for your simulations.
