Abstract Relative Effective Annual Precipitation (REAP) values were developed for each Montana county and Yellowstone Park by the Natural Resources Conservation Service Montana State Office (NRCS). DAYMET precipitation data from the University of Montana were verified/adjusted to the 30-year precipitation data period from the National Water and Climate Center and then sensitized to the landscape according to slope and aspect. This was calibrated by soil scientists to known vegetation breaks on the landscape based on imagery, experience in assigned areas, and published SSURGO/NASIS soils data.
Purpose For display of relative effective precipitation values across Montana and input into decision processes that require knowledge of effective precipitation values.
