1 runningHelp build a community rainfall dataset. Each day, check your rain collector and record what you observe. Each week, confirm your setup and results.
Your daily readings automatically roll up into weekly totals, rainy/dry day counts, highest rainfall and averages. Accurate, honest observations โ including "no rain" and "missed" days โ matter just as much as big numbers.
