Description
I added the new observation sensitivity driver (OBS_SENSITIVITY) which quantifies the impact that each observation has on the 4DVAR data assimilation system. By measuring the sensitivity of the data assimilation system to each observation, we can determine the degree to which each observation contributes to the uncertainty in the circulation estimate. This analysis can help us to determine the type of measurements that need to be made, where to observe, and when. See the following wikiROMS page for more technical and mathematical formulation.
Many thanks Andy Moore for his help developing this new driver. This driver is still under testing. We will let you know in the future when it is ready to use.
I also updated the 4DVAR adjustment of surface forcing fields. Many thanks to Gregoire Broquet for his continuous help debugging this algorithm.
