STEM Aerosol and Trace Gas 4D Model Forecast Products



This dataset contains daily chemical weather forecasts from the STEM regional chemical transport model provided by the Center for Global & Regional Environmental Research, at the University of Iowa, in support of the PACific Dust Experiment (PACDEX). The model runs were performed at 50km horizontal grid resolution. The Weather Research & Forecasting (WRF) model provided meteorological fields to drive the STEM model transport. This dataset contains daily STEM model 3d output files and back-trajectories intiated every minute at aircraft flight altitude.
