ICON-ART: Corinna Hoose and Ali Hoshyaripour

Aerosol and Reactive Trace gases (ART) is a component of the ICON modeling framework that enables explicit treatment of atmospheric composition and its interactions with clouds and radiation. ART encompasses emission, transport and removal processes of trace gases and aerosols in the troposphere and stratosphere along with their transformations due to chemistry and aerosol microphysics.

HAMMOZ (Hamburg Aerosol Module and atmospheric chemistry code MOZART)

Anne Kubin

HAMMOZ contains a detailed representation of tropospheric-stratospheric chemistry and state-of-the-art parameterizations of aerosol using either a modal (M7) or a bin scheme (SALSA). The aerosol model HAM calculates the dispersion and evolution of the mass and number concentrations of an aerosol mixture considering the species sulphate, black carbon, organic carbon, sea salt and mineral dust. The standard version of HAM describes the aerosol size spectrum through the modal M7 aerosol model, which simulates a superposition of seven lognormal modes: Nucleation mode, Soluble (mixed) and Insoluble Aitken, Accumulation and Coarse modes. Each aerosol mode is assumed to be internally mixed, so that individual particles in a mode can be mixtures of different species. Insoluble particles can become mixed (soluble) by condensation of soluble substances and by collisions with mixed particles.
