Mountain Rain or Snow
During winter storms, tell us what is falling from the sky.
Scientists need your help to better understand winter weather. It's notoriously difficult to research winter precipitation in the mountains because it can vary over the course of minutes and across short distances. Few weather stations can accurately identify precipitation phase near freezing (rain, snow, or mixed).
Direct observations, made by people, are the most accurate way to discover how precipitation phase varies in time and space. Start reporting with the Mountain Rain or Snow app during winter storms to help improve the technologies behind precipitation phase prediction.
