Welcome to the homepage for the Data Assimilation Team. We were established within RAL's Joint Numerical Testbed in August 2006 to provide an environment for the objective testing and evaluation of state-of-the-art data assimilation techniques as applied in real-world numerical weather prediction applications. The DATC is also intended to complement the activities of the Developmental Testbed Center (DTC) by providing support, testing and evaluation of the data assimilation component of the Weather and Research Forecasting (WRF) modeling system.
The current scope of the Data Assimilation Team includes:
The scope of the DATC is evolving as new applications appear.
The DATC was initiated as a joint collaboration between NCAR and the Air Force Weather Agency (AFWA) in 2006. Since then, the DATC has become an international effort supported by AFWA, NCAR's Antarctic Mesoscale Predictions System (AMPS), the Korean Meteorological Administration (KMA) and Taiwan Civil Aeronautics Administration (CAA). Testbeds have been built to test and evaluation data assimilation components in various applications. Details of these projects can be found in the projects list to the right of this page.
