CAMx simulation setup

WRF-ARW fields preprocessing

CAMx v6 meteorological input files from WRF-ARW core output files keeping original WRF fields were generated considering several improvements:

  • Kv computation by means of YSU scheme
  • Subgrid convection: sub-grid clouds diagnostic from gridded met fields
  • Stratiform scheme: sub-grid stratiform cloudiness diagnostic
  • Enhancement of vertical mixing via vertical diffusivity
  • Landuse-based patch to enhance mixing over urban areas.
  • Expansion of the daytime PBL Kv profile through capping

cloud tops as a means to prohibit artificial collapse of the boundary layer when convection develops and to include convective venting to the free troposphere.

CAMx – Sensitivity analysis

  • Base case configuration (RSE) [today and tomorrow…]
  • KV scheme changed in WRFCAMx (from YSU to CMAQ)

(ARPAV) [tomorrow…]

  • nested domain switched off (influence of resolution on

SA results) (UAVR) [tomorrow…]

  • evaluate Organic aerosol trough VBS instead of SOAP (RE)

[coming soon…]

Methodology – Short Description

  • Biogenic Emissions (BVOCs)
  • Calculation of isoprene “synthesis” emissions (depending on both temperature and

light) and monoterpene and OVOC “pool” emissions (depending on temperature

  • nly)
  • leaf age, soil moisture and seasonality correction factors
  • Windblown Dust (WD)
  • Estimation of the horizontal (saltation) and the vertical (fine suspended particles)

dust flux

  • Parameterization of threshold wind speed as a function of soil particle size, soil

moisture and drag partitioning

  • Sea Salt Aerosols (SSA)
  • The SSA production is dependent on wind speed, sea surface temperature and

water salinity

  • Primary Biological Aerosol Particles (PBAPs)
  • Emission factors for plant debris and fungal spores emissions
