What is the Rainfall Roundup?
This is an effort to organize a cooperative rainfall monitoring network across Arizona. Data collected through this network will be used in drought monitoring programs at the county, state, and national levels. Why do we need more rainfall data? Precipitation amounts are highly variable through space and time across Arizona due to topography and seasonal weather patterns. This is especially true during the monsoon season when thunderstorms can produce heavy rainfall events that are very localized.
