UAE Research Program for Rain Enhancement Science

The internship application for the UAEREP summer 2024 internship at CW3E is open now!

Project Brief

This project proposes to use artificial intelligence (AI) to improve precipitation estimates
and pave the way for enhanced forecasting and cloud targeting by leveraging vast ground-based and spaceborne data sets and operational numerical weather prediction products from national meteorological centers worldwide. With the unprecedented abundance of data sets from diverse observations and models available to operational rainfall enhancement programs, the exploration of AI algorithms already results in significantly improved weather forecasts.

This project aims to create an AI research and operations testbed in the UAE. This entails building a novel AI framework to blend satellite observations, ground-based weather radar data, rain gauges, and numerical weather prediction estimates to extract features and generate products to determine optimal cloud seeding timing and location, and to generate more accurate quantitative precipitation estimation for rainfall enhancement program evaluation. An advanced deep learning algorithm is proposed to learn from several thousands of examples from historical data how to effectively extract and extrapolate inputs and the required cloud features necessary to define seedable cloud patches. These features and inputs, along with extrapolated satellite and radar data, numerical weather prediction data, and rain gauges, are utilized as input to an AI-based model to generate precipitation predictions six hours in the future.

To expand rain enhancement capabilities in the UAE through AI and existing assets, this project assembled a multidisciplinary and diverse research team led by the Scripps Institution of Oceanography at the University of California San Diego with collaborators from Khalifa University and Colorado State University. The main deliverable at the end of the project will consist of a prototype of the AI-based predictive capabilities. The prototype will be deployed at the National Center for Meteorology (NCM) in the UAE through a research and operations partnership.
