I n t e g r i t y - S e r v i c e - E x c e l l e n c e 12 While the Space Flight has considerable capability, the 4-D data cube has not been fully realized AFWA lacks predictive models for several domains Much modeling capability is based on conditional climatology driven by global indices… Need to move to physics-based modeling and data assimilation as technology allows Many domains are severely under sampled Some shortfalls driven by a lack of basic research understanding AFWA utilizes an aggressive technology transition process to combat these shortfalls Partnerships are again crucial Shortfalls
