DATC CAA Testbed

The Taiwanese Civil Aeronautics Administration (CAA) Testbed is a pre-operational test-rig to evaluate the CAA WRF-ARW and WRF-Var system in Pacific applications. Major work includes studies of radio-occultation data impacts, radiance data assimilation tuning, and radiance data impacts on typhoon forecasts, etc.
