Aspect

This layer represents aspect (units=degrees) calculated from elevation data obtained from the PRISM climate group, distributed by Climate Source. From personal communication with Wayne Gibson, it was "based off of GTOPO30 data, and then Barnes filtered to the desired resolution"

SNAP resampled the 2km elevation product to the 1km model resolution by bilinear interpolation, and then calculated aspect.
