In a major scientific breakthrough with direct relevance to climate resilience, the Cochin University of Science and Technology (CUSAT) has secured a national patent for a new machine learning-based technology that can accurately extract rainfall information from atmospheric radar signals. The innovation, developed at the university’s Advanced Centre for Atmospheric Radar Research (ACARR), is expected to transform how weather is observed, analysed and predicted in Kerala — a state repeatedly tested by floods and extreme monsoon events.

The new system merges advanced signal processing with artificial intelligence to solve one of the oldest challenges in radar meteorology — separating echoes from falling raindrops and those generated by atmospheric
