This page is part of the Aerosol Model (SALSA) documentation.
It contains a description of SALSA.
For an overview of all SALSA-related pages, see the SALSA main page.
In SALSA, the aerosol size distribution is represented as a discrete set of size bins (by default 10 bins). The number ni (m-3) and mass concentration mc,i (kg m-3) of each size bin i and chemical component c are the model prognostic variables. Currently, the following chemical components can be included: sulphuric acid (H2SO4), organic carbon (OC), black carbon (BC), nitric acid (HNO3), ammonium (NH3), sea salt, dust and water (H2O). Furthermore, the gaseous concentrations of H2SO4, HNO3, NH3 and semi- and non-volatile organics (OCNV and OCSV) are also default prognostic variables. The aerosol dynamic processes included are coagulation, condensation of H2SO4, organics and water vapour, dissolutional growth by HNO3 and NH3, nucleation and dry deposition on horizontal and vertical surfaces and resolved vegetation.
SALSA can be coupled with the chemistry module. In that case, the five gaseous compounds (H2SO4, HNO3, NH3, OCNV and OCSV) will be imported to SALSA from the chemistry module and should thus be included in the chemical mechanism applied. Example
SALSA is enabled by adding the NAMELIST salsa_parameters with appropriate parameters to the INPUT parameter file (<run_identifier>_p3d).
