Free rain log for your site
Enter a site address. You get its storm history from NOAA MRMS data, with the inspection-clock calendar and a printable log. No account needed.
How it works: RainClock samples NOAA MRMS 1-km precipitation at your site coordinates every hour and keeps the per-event record your permit's rain documentation requires (EPA 2022 CGP Part 4.2.2). History builds from the moment a site is on the log.
