Last change on this file since 4131 was 4131, checked in by monakurppa, 2 years ago

Several changes in the salsa aerosol module:

  • Add "salsa_" before each salsa output variable
  • Add a possibility to output the number (salsa_N_UFP) and mass concentration (salsa_PM0.1) of ultrafine particles, i.e. particles with a diameter smaller than 100 nm
  • Implement aerosol emission mode "parameterized" which is based on the street type (similar to the chemistry module).
  • Remove unnecessary nucleation subroutines.
  • Add the z-dimension for gaseous emissions to correspond the implementation in the chemistry module
  • Property svn:keywords set to Id
