The ACME project will exploit the measurements of clouds from different marine environments:
over the Mediterranean Sea during the EXAEDRE campaign (autumn 2018, Corsica),
over the North Atlantic Ocean during the HAIC campaign (May 2015, French Guiana),
and over the South Pacific Ocean during the Sea2Cloud campaign (March 2020, New-Zealand).
These different observations help to better constrain the representation of the primary and secondary ice nucleation mechanisms (i.e. heterogeneous and homogeneous ice nucleation as well as the secondary ice multiplications) in the bin cloud-scale model DESCAM (DEtailed SCAvenging Model) which has been developed in LaMP (Laboratory of Physics Meteorology) since the 80’s (Flossmann and Wobrock, 2010).
After the improvements of the representation of ice formation mechanisms, this unique numerical tool for aerosol-cloud interaction studies will allow us to reach the ACME objectives.
