High-Fidelity On-Demand NWP Modeling at GTRI for Atmospheric Propagation Applications
Meteorologists at Georgia Tech Research Institute (GTRI) leverage High Performance Computing (HPC) infrastructure to perform tailored high-resolution Numerical Weather Prediction (NWP) modeling, simulation, and analysis (MS&A). Here we document our development of multi-timescale prediction capabilities and evaluate their potential utility for supporting Directed Energy Weapon (DEW) test & evaluation (T&E) events. Focusing on optical turbulence which impacts optical propagation, we present a comparison of three modeling approaches: (1) our baseline simulations with well-assimilated initial and boundary conditions, (2) simulations driven by operational weather forecast model outputs intended for near-term event planning and site assessment, and (3) simulations utilizing seasonal climate model outputs intended for long-term event planning choosing between alternative weeks or sites. We evaluate uncertainties propagated from operational forecast models and assess how these uncertainties constrain the utility of site-specific NWP modeling for planning T&E events.
