Precipitation Downloader Module
===============================

Download precipitation data for rainfall-weighted flow accumulation.

This module provides functions to download precipitation data (e.g., PRISM)
for use in hydrological analysis. Precipitation data enables rainfall-weighted
flow accumulation, which produces more realistic discharge estimates than
simple cell-count accumulation.
