Missed Observations PDF
Not home to take your observations? Whether you take a vacation, oversleep, or just didn't want to risk being struck by lightning, we do not expect observers to take their readings every day of the year for the rest of their lives! However, we can take steps to keep the precipitation record as accurate as possible by listing the time span that a report covers. Multi-day precipitation reports allow observers to enter the amount measured over two or more days.
  1. Visit the website www.cocorahs.org and click "My Data" on the top right section of the page.
  2. Click "Multi-DayAccumulation" on the menu on the left side of the screen.
  3. Enter date forfirst day you missed your observation First day of accumulation period.
  4. Enter date you took your observation
  5. Fill out remaining observation details.
  6. Click "Submit".
For example, I will be traveling to my parent's house for Thanksgiving and will not be around to read my gauge and I do not have a reliable neighbor or friend to take the readings for me. I took my reading Tuesday morning, November 24, and entered my data as usual. I returned from my trip Sunday night and took my reading Monday morning (November 30). In this case, I would enter 11/25/2009 as my first date first day that I missed, and 11/30/2009 as my end date (date I took observation).
