At the time of writing, aggressive development is underway toward improving several aspects of the system to address user concerns and noted biases. This includes, but is not limited to, changes to the background error model to contain a representation of flow dependence as well as continued enhancements to observation quality control. In addition, a method for nimble blacklisting of bad observations through user engagement is in progress.
Recent upgrades, including RU-RTMA, as well as near term plans and progress will be discussed. Longer term plans toward the development of a 3D RTMA/URMA system with sub-hourly updates will also be presented.
