Bighorn Mountains Dendrochronology

Meteorological data

These data have been used to determine tree ring climate relationships. Files are in the Tucson meteorological data format and can be used with the Dendrochronology Program Library. Missing values in most of these single stations files were estimated from values in a network of stations using the DPL program MET. Click on the filename to download a data file.
