Welcome to the iRain app, developed by the University of California Irvine. iRain provides access to real-time global high-resolution satellite precipitation products from the PERSIANN-CCS algorithm. This algorithm has been developed by the research team at the Center for Hydrometeorology & Remote Sensing (CHRS) at UCI and has been under development for over two decades.

With iRain, users can visualize real-time global satellite precipitation observations and track extreme precipitation events globally. The app also offers a crowdsourcing functionality that allows users to report their local rainfall information to supplement the data.

The iRain app is a valuable tool for anyone interested in monitoring and understanding global precipitation patterns. It is especially useful for researchers, meteorologists, and weather enthusiasts. Experience the power of real-time satellite precipitation data with iRain UCI.
