STEM Aerosol and Trace Gas 4D Model Forecast Products
Listed in National Center for Atmospheric Research
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).
Description
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.
