- Abstract
The Lagrangian particle dispersion model (LPDM) FLEXPART includes a parameterisation of wet scavenging. With FLEXPART version 8, an improved scheme was introduced which distinguishes between in-cloud and below-cloud scavenging. However, clouds are only diagnosed from grid-scale variables and thus convective clouds are neglected. Although the convection scheme of Emanuel and Živković-Rothman (1999) already implemented in FLEXPART provides this convective cloud (and precipitation) information, it is just used for convective redistribution of computational particles by deep convection. Convection parameters diagnosed from this convection scheme are investigated with the aim to improve the wet scavenging in FLEXPART by using convective cloud parameters.
