Objective:
The goal of this research is to develop and evaluate the assimilation of remotely-sensed datastreams into a coupled hydrological/meteorological modeling system using high-performance computing-based parallel techniques. The research is multifaceted, making use of two state-of-science predictive numerical models?MM5 and TOPLATS?coupled so as to enable the modeling of the land-atmosphere system as a whole.Progress Summary:
During the second year (1998), we: (1) completed the model coupling computational infrastructure; (2) completed the basic physics modifications needed to couple the models in 1-D and continued our analysis and development of aggregation and disaggregation approaches; (3) completed and analyzed an array of 1-dimensional coupled model runs, performed sensitivity experiments, and have obtained encouraging results; (4) are nearing completion of the 3-D coupling of the two models; (5) installed and are using appropriate analysis/visualization tools for the modeling system; and (6) prepared, presented, and published numerous conference papers on our work, presented additional seminars, participated in U.S. Environmental Protection Agency (EPA) focus groups with interest in the project, and are preparing two journal articles for publication. In addition, we have: (7) continued our work on database development; (8) built new collaborations as a result of the project; and (9) continued to assure project quality.
