Values of relevant PRISM interpolation parameters.

* Expands as needed to encompass minimum number of total stations desired in regression (st).+ Slope is expressed as the change in dew point depression (DPD) per unit Tmin from the predictor grid# Slope is expressed as the change in VPD per unit first-guess VPD from the predictor grid$ Units are effective distance in grid cells from the coast, incorporating terrain barriersRegression slope bounds are sometimes different among regions; values separated by forward slashes are for west, central, and east regions, respectively. See [7] and [8] for details on PRISM parameters and Table 3 for citations to details on weighting function formulations.
