Just 100 Observations

If you are a new observer or even if you have been making CoCoRaHS observations for awhile, you may not be aware of the significance of 100 daily observations.

When you have made 100 daily precipitation observations (multi-day reports not included) the data from your station becomes part of the CoCoRaHS data archived by the National Centers for Environmental Information (NCEI). Daily CoCoRaHS observations are ingested into the Global Historical Climate Network-Daily archive, the data set that includes all daily data from U.S. Cooperative network stations, airport weather stations, and CoCoRaHS. CoCoRaHS is the largest source of daily precipitation observations in the U.S., so you can see how important CoCoRaHS and your observations are to painting the national picture of precipitation throughout the United States. Precipitation normals are also calculated for CoCoRaHS stations based on their longevity and consistency of observations, a valuable addition to the climatology of precipitation across the country.

Once you have submitted 100 daily observations - 100 days, 13 weeks, or a little more than three months - your observations become part of the climate history of your locale, your state, and the country. When you reach that milestone (or shortly thereafter) your accomplishment will be recognized with a certificate from CoCoRaHS headquarters. 

Future milestones (250, 500, 750, 1000, 1500, 2000, 2500, 3000, and every 1000 to 8000+ observations) will also be recognized with a certificate.

Make your observations a daily habit. Be sure to report each day (zeroes are data, too) and you will be part of U.S. climate history!
