As Arizona’s land-grant university, we are driven to do great things. It’s our passion to transform the lives of our student Wildcats and to solve some of the biggest challenges facing our state and the world.

But what makes us unique is how we do it. We live our purpose, mission and values every day. And we do this in one of the most incredible places on Earth, surrounded by majestic mountains and Saguaro forests, and under a sky that ignites imaginations with cotton candy sunsets and diamond-filled nights. At the University of Arizona, everywhere you look is filled with wonder.

These maps are focused on capturing unique elements of the summer monsoon season hydroclimate across Arizona and New Mexico including total precipitation, intensity, and frequency of precipitation events. Maps are updated once a day from June 15 - September 30th using gridded PRISM precipitation data (nominally 4km by 4km) provided by the Applied Climate Information System (RCC-ACIS). The daily data represent the 24 hour total precipitation measured at 12:00 UTC (locally 5:00am Mountain Time). PRISM data availability is lagged by one day so totals through 12Z of the previous day are available here. The gridded data provide a spatial estimate of true precipitation amounts across the region and should be interpreted with caution at very fine scales.
