- Obtaining and installing an official CoCoRaHS 4-inch rain gauge (available only from two suppliers; follow the links on the CoCoRaHS website to view and purchase)
- Checking the gauge and filing daily precipitation reports through the CoCoRaHS website
An introductory slide show is available for viewing on the CoCoRaHS training page.
