Description
The observation impact for 4D-Var drivers was updated:
- Added the observation impact operator for IS4DVAR in driver obs_sen_ocean.h. It includes capability to compute the contributions due to initial conditions, surface forcing, and boundary conditions using the OBS_IMPACT_SPLIT option.
- Added missing code for the balance operator in obs_sen_ocean.h.
- Corrected the IO logic in obs_sen_w4dpsas.h and obs_sen_w4dvar.h to distinguish between observation sensitivity and observation impact. The ouput when OBS_IMPACT_SPLIT was not activated was missing for the obsevation sensitivity option.
Many thanks to Andy Moore his help in coding and testing this algorithms.
