Climate and Weather Research and Evaluation Testbed (CAWRET)
About CAWRET
Hosted by A*STAR in partnership with the National Supercomputing Centre (NSCC) Singapore and Centre for Climate Research Singapore (CCRS), the Climate and Weather Research and Evaluation Testbed (CAWRET) under the Climate and Weather Research Alliance Singapore (CAWRAS), provides researchers with access to comprehensive observation datasets, advanced modelling capabilities, and supercomputing resources essential for compute-intensive weather and climate research.

CAWRET will help facilitate cross-institute collaborative research through common configurations (domain of interest, resolution, time periods , etc.), enabling robust evaluation of new weather prediction capabilities against standard benchmarks (e.g. impact on forecast skill of research advances measured against the Meteorological Service Singapore (MSS) standard scorecard of key weather parameters and forecast ranges), helping to enhance Singapore’s weather resilience.
