More on project SMARTER

Heavy rain and hail are very localized and fast-developing threats responsible for millions in damages every year. To reduce losses, better detection and warning systems must be put into place. Unfortunately, operational radar networks in Europe are still too rigid and slow to adequately predict heavy rain and hail. Rather than collaborating with each other, radars mostly operate independently from the others in a traditional sit and spin fashion. The lack of coordination between radars leads to long revisit times and sub-optimal data collection strategies. 


What is the problem?

Project SMARTER (Strategic Monitoring of Atmospheric Threats using Enhanced Radar) is a NWO funded project aimed at making weather radar networks more adaptive and collaborative. Instead of operating independently from each other, individual radars will be given the ability to react to developing threats (e.g., heavy rain or hail) and change the way they scan or acquire data. The main challenge in building a collaborative radar network is the complexity of the decision space. At any given time, there are thousands of possible adjustments for each radar, and no obvious way of knowing which decisions are best for the network as a whole. To overcome this issue, we want to build a general mathematical framework for understanding closed-loop control in radar networks as well as an innovative optimization approach for choosing the best radar control parameters in real-time based on a large number of simulation experiments and reinforcement learning techniques.

How can we solve this?

This new adaptive scanning technology will allow scientists to get more detailed insights into the physics and dynamics of heavy rain and hail, which are key for improving the accuracy and timeliness of forecasts. A proof-of-concept of this cognitive loop for collaborative radar networks will be implemented in the Delft-Rotterdam area, taking advantage of a brand-new, state-of-the-art infrastructure for atmospheric research known as the “Ruisdael observatory”.
