註釋

Regression trees have been applied to snow water equivalence (SWE) measured in the field in several alpine basins of the Sierra Nevada. The independent variables used were: net solar radiation, elevation, slope angle, and vegetation cover type. The regression tree models proved to be effective in modeling the spatial distribution of SWE in alpine basins. Net solar radiation was the most important independent variable in almost all model results. Elevation and slope were of second and third order importance and vegetation played a reduced role. Results showed that in complex alpine terrain the mean of field measurements is often not a good estimator of mean basin SWE conditions because the irregular terrain causes a strong spatial dependence in SWE distribution. -- Adapted from abstract.
