Opportunity Description

Title of Research Opportunity: Quantifying Uncertainties in Microscale Meteorology A postdoctoral research opportunity is available at the Army Research Laboratory (ARL) in the Battlefield Environment Division of the Computational and Information Sciences Directorate. ARL is seeking candidates with a background in uncertainty quantification (UQ) to conduct research in uncertainty quantification for battlefield meteorology. The opportunity will be located at Adelphi, Maryland. ARL is developing methodologies for predicting uncertainty in battlefield weather forecasts that, when incorporated into tactical decision aid tools and smart agents, will give Warfighters the ability to quickly assess with confidence any potential meteorological effects on Army systems and personnel. The focus is on developing such methodologies for microscale meteorology with short-term forecasts out to at most 6 hours. ARL is looking for scientists to aid in this research. The most prominent challenge in carrying out this UQ analysis is the cost of executing the high-fidelity, microscale model. To faithfully model uncertainties in the predictions, a large number of random parameters are needed. This casts the problem into a high-dimensional, random parameter space. To fully explore this space for accurate UQ analysis, an extraordinarily large number of samples are required; however, each sample corresponds to a full-scale deterministic simulation. Time and the cost of executing the high-fidelity model precludes its widespread use in the UQ analysis, therefore, other approaches are needed, such as using reduced-order-models or other means to explore this space. The goal is to develop computational tools and methodologies that enable fast and accurate UQ analysis of this problem.
