Atmospheric Sciences Department and the Fairbanks Museum are jointly
coordinating efforts in the northeast kingdom region of Vermont.
What is it?
CoCoRHaS is a network of volunteers taking precipitation observations
across the country. Vermont's participation is headed up by the National Weather Service office in Burlington, VT.
CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and
Snow Network. CoCoRaHS is a unique, non-profit, community-based
network of volunteers of all ages and backgrounds working together to
measure and map precipitation (rain, hail and snow). The network originated with the Colorado Climate Center at Colorado
State University in 1998 thanks in part to a flood in Fort Collins the prior
year. In the years since, CoCoRaHS has expanded rapidly with over
12,000+ observers in thirty-nine states.
CoCoRaHS has several goals (as stated in the CoCoRHaS mission statement).
- Provide accurate high-quality precipitation data for our many end
users on a timely basis;
- Increasing the density of precipitation
data available throughout the country by encouraging volunteer weather
- Encouraging citizens to have fun participating in
meteorological science and heightening their awareness about weather;
- Providing enrichment activities in water and weather resources for
teachers, educators and the community at large to name a few.
How can I participate?
will take measurements of precipitation
from many different locations. These precipitation reports are then recorded
on the official CoCoRHaS website.
The data are then displayed and organized for many of our end users to
analyze and apply to daily situations ranging from water resource
analysis and severe storm warnings to neighbors comparing how much rain
fell in their backyards.
All that is required is that you measure precipitation at your home once a day
and enter that information on the CoCoRHaS web site. Typically, this will be
done in the morning such as before you would leave for work or go to school.
It only takes a couple of minutes to complete each day. Once you are a member
of the network you will be able to see your data on the national CoCoRHaS
website, and compare your observations with other participants.
