Estimating volcanic ash emissions using retrieved satellite ash columns and inverse ash transport modelling [PDF]
arXiv, 2020 This paper describes the inversion procedure being used operationally at the Norwegian Meteorological Institute for estimating ash emission rates from retrieved satellite ash column amounts and a priori knowledge. The overall procedure consists of five stages: (1) generate a priori emission estimates; (2) run forward simulations with unit ...
