Swapping precipitation collectors in the Rockies

Daniel Bowker, Loch Vale project manager (2013-18), swapping a clean precipitation collector with a collector from the previous week in Rocky Mountain National Park.

Loch Vale is one of 250 sites in the National Atmospheric Deposition Program/National Trends Network (NADP/NTN). Precipitation samples are collected weekly to present local and national data of pollutants and other chemicals in rain and snow since 1978.
