Abstract : The purpose of this study was to upgrade the emergency response atmospheric modeling capabilities at Vandenberg Air Force Base (vAFB) with state-of-the-science three-dimensional forecast models adopted on an advanced scientific workstation. The contractor added new capabilities to HOTTAC (Higher Order Turbulence Model for Atmospheric Circulation) and RAPTAD (Random Puff Transport and Diffusion) to meet the objective of the project. Specific improvements included nested grids four-dimensional data assimilation, incorporation of tower data, radiation transfer in clouds, precipitation microphysics, and positive and negative buoyancy plumes. The HOTMAC and RAPTAD modeling system was installed and tested on a workstation. The whole modeling system was delivered to VAFB for further tests.
