Description

This dataset consists of UCLALES-SALSA model output of the experiments presented in the manuscript "Can pollen affect precipitation?" by Prank et al. and the model code used for making these simulations. Simulations were made for two cases, one for warm cumulus (RICO) and one for mixed-phase stratocumulus (Puijo) with a range of pollen emission fluxes.

Methods

UCLALES-SALSA combines the widely used UCLA Large Eddy Simulator with a detailed aerosol-cloud microphysics model SALSA, that includes sectional representations of aerosols, liquid cloud droplets, raindrops and ice and simulates their interactions. The model was amended with parameterizations for pollen emission and humidity dependent rupture.
