The Met Office has developed a 3D variational (3D-VAR) data assimilation system based on the stratosphere-?troposphere configuration of the United Model. The stratosphere-?troposphere data assimilation system is based on the version used for the standard operation global forecast model, which was implemented in March 1999. The 3D-VAR assimilation system described here replaced the former Analysis Correction (AC) assimilation system in November 2000. This paper describes both the impacts of moving from the AC to VAR, and of adding additional stratospheric levels to the standard global data assimilation system.
