| Popis: | The new version of FALL3D has recently been released with several new features and improvements in model physics, solving algorithms, code accuracy and performance [1]. Among the new features are a data insertion scheme and the ability to simulate volcanic SO2 clouds. The data insertion scheme enables users to initialise model runs from satellite retrievals. This modelling approach is useful for removing uncertainties associated with source term parameters such as the mass flow rate, plume height, source duration and start time. Here we demonstrate and validate the new data insertion scheme in FALL3D-8.0 using geostationary satellite retrievals of volcanic ash and SO2. |
