About this app

Welcome to the iRain app. The app is licensed to the Center for Hydrometeorology & Remote Sensing (CHRS) at the University of California Irvine (UCI).

iRain provides access to real-time global high-resolution (~4km) satellite precipitation products from the PERSIANN-CCS (Precipitation Estimation from Remotely Sensed Information using the Artificial Neural Networks - Cloud Classification System), which has been developed by the research team at CHRS. The building block of iRain rests on the satellite precipitation estimates generated by the PERSIANN algorithm which has been under development for over two decades. More detailed information about PERSIANN-CCS can be found at http://chrs.web.uci.edu.

iRain allows users to visualize real-time global satellite precipitation observations and track extreme precipitation events globally. Users can also use the crowdsourcing functionality of the app to report their local rainfall information to supplement our data. A useful feature of iRain is that real-time rainfall observation data can be easily shared through social networks i.e. Facebook, Twitter.
iRain is available for iOS and Android devices.
The web version of iRain is hosted at:

Acknowledgments:
iRain is the product developed by Dr. Phu Nguyen, Assistant Adjunct Professor in the Center for Hydrometeorology and Remote Sensing (CHRS) at UCI and his team, which includes a dedicated group of mostly undergraduate students including David Furman, Phat Huynh, Thanh N. Palacios, Hoang Tran, and April Huie.

Financial support of the following agencies is acknowledged:

- NASA funding resulted in the development of the PERSIANN algorithm and several of its variations.
- ICIWaRM of the US Army Corps of Engineers has provided a major part of support for Mr. Dan Braithwaite, Programmer Analyst III at CHRS.
- The US Army Research Office’s support has resulted in additional refinement of the PERSIANN algorithm
- Cooperation with UNESCO’s G-WADI program has been critical to the dissemination of data worldwide.
- NOAA funding through the Climate Data Record (CDR) program resulted in the PERSIANN-CDR dataset.

The following members of CHRS (former and current) are greatly acknowledged.
Kuolin Hsu, Xiaogang Gao, Bisher Imam, Dan Braithwaite, Hamed Ashouri, Andrea Thorstensen, Scott Sellars, Ali Behrangi.

Special thanks to Hien To, Ph.D. student at USC, for his contribution on the crowdsourcing technologies.

Ratings and reviews

I am a user, and I sincerely request you to release a new update within this month that allows us to see how many millimeters of rain will fall in the next 1, 3, 6, 12, 16, 20, and 24 hours and where. Bringing such an update would be extremely helpful for us. This is my heartfelt request to you.

On Android device, it simply does not work any more. After deleting the old version and loading latest version , I still get "unable to retrieve data lag time " message, same as before.

Very good application, but do not work on all android version. This app show you the aqumolative rain in last three days. Using this application beside FLOWX will help you to prevent human life and their assets. By this application you see the past three days rainfall and with FLOWX you cao see the nest week rain fall in specific location. You have time to do action against mother nature. Try it.
