Modelling of Tropical Tropospheric Chemistry

The junior research group has been examining several aspects of tropical tropospheric chemistry using two 3D models. Here an overview of the results is given, focusing particularly on two central activities of the group: 1) the outflow of pollutants from southern Asia and the factors controlling pollution over the Indian Ocean; 2) the role of deep convection in tropospheric chemistry, especially in the tropics, and its treatment in cloud-resolving and global models.
