Wow, 4,779 that is great
I received mine with 2,291 continuous observations (including a few multi-day reports for the period we were away from home).
What manually .. every day? And that's all you have to show for it, what do they get out of it?
They get to share it with many authorities... like conservation and environmental authorities, and agricultural organizations. For example last year I was contacted and interviewed by our Province's environmental agency who were referred to me by CoCoRaHS in their investigation of a contaminant spill in the nearby Thames River and wanted to get accurate manual rainfall for some specific days. The company that caused the spill was using the extreme weather/rainfall excuse. In this case my 24-hour CoCoRaHS records matched closely to my Davis VP2/Cumulus records which has the 5-min interval log.
Enjoy,
