Inclusion of ash and SO2 emissions from volcanic eruptions in WRF-Chem: development and some applications
We describe a new functionality within the Weather Research and Forecasting (WRF) model with coupled Chemistry (WRF-Chem) that allows simulating emission, transport, dispersion, transformation and sedimentation of pollutants released during volcanic activities. Emissions from both an explosive erupt...
