Mission:
The mission of this working group is to develop a robust, efficient and flexible WRF 4-D variational assimilation system for use by both operational and research communities. Specific 4DVAR tasks supplement those of the WRF 3DVAR system and include:
* Perform an early assessment of the possible use of automatic differentiation tools.
* Develop a forecast model for the evolution of small yet finite perturbations (tangent-linear/perturbation forecast model) - including the representation of significant physics (components TBD) as well as dynamics.
* Develop the adjoint code for the perturbation forecast model.
* Include representation of model error evolution.
* Merge the above with the WRF 3DVAR system.
* Inclusion of high-frequency/resolution observations e.g. radar, automated surface stations, satellite.
