Since 2009, nearly 300 New Hampshire citizens have joined CoCoRaHS New Hampshire to provide agencies, educators, researchers and the public with daily observations of rain and snow. This network of volunteer weather observers has reported thousands of precipitation observations spanning three tumultuous years in which New Hampshire was battered by historic storms including Tropical Storm Irene and the snowstorm of October 2011. CoCoRaHS observers also participate in other observation networks including the NWS COOP Program
and provide researchers with daily snow reflectivity (albedo) measurements
as part of the NH-EPSCoR funded project entitled "Climate Forcing of Surface Albedo in New Hampshire and Northern New England."
Snow-surface albedo observations available at: CoCoRaHS-Albedo
We thank all of our observers from Portsmouth to Keene, across the Lakes Region and the White Mountains, to the Northern edges of Coos County who have helped us better understand and prepare ourselves for what New England weather has in store for us. Please continue to help us measure precipitation by reporting every day because we know that "Every Drop Counts."
