Short summary
An inversion method is tested in a forecasting setting for constraining ash dispersion by satellite observations. The sensitivity of a priori and satellite uncertainties is tested for the a posteriori term. The a posteriori is also tested with four different assumptions affecting the retrieved ash satellite data. In forecasting mode, the a posteriori changes after only 12 h of satellite observations and produces better forecasts than a priori.
