EURODELTA-CARB model experiment, BaP Phase

Participants:

Coordination

  • Augustin Colette (INERIS, TFMM Chair)

Modellers:

  • MSC-E/EMEP : Alexey Gusev
  • INERIS/Chimere : Florian Couvidat
  • FMI/SILAM: Rostislav Kouznetsov, Evgeny Kadantsev
  • ENEA/MINNI: Mihaela Mircea, Ilaria Delia, Mario Adani
  • IASS/WRF-CHEM: Aura Lupascu (tbc)
  • IEP/GEM-AQ: Joanna Struweszka (tbc)

Analysis:

  • MSC-E/EMEP : Alexey Gusev
  • CIEMAT/CHIMERE: Marta Garcia Vivanco

Observations

  • CCC/NILU: EMEP observations
  • EEA/ETC: AQ e-reporting data

Background

Main motivation:

  • Model intercomparison / performances for BaP, also in relation with modelling of correlated species: PM, EC, levo
  • Reference BaP levels for exposure assessment in relation with EU target levels
  • Link BaP with PAHs in general in relation with Gothenburg Protocol Review
  • Sensitivity to modelled processes

Modelling experiment

Annual simulation encompassing IMP field campaing in the winter of 2017/2018 Referred to as Experiment “E” of Eurodelta-Carb PM modelling phase, with adaptation in the model technical specifications below

Technical Specifications

all input/output data are on ftpmoca.ineris.fr, contact augustin.colette@ineris.fr for login details

Model Setup

  • Geographical domain: 0.1 deg resolution, 25°W-45°E, 30°N-72°N
  • Time period: 20171201-20181231 (excluding spin-up)
  • Meteorology: IFS recommended (exceptions allowed)
  • Boundary Conditions: C-IFS recommended (exceptions allowed)

Emissions:

  • Spatialised BaP 2018 emissions delivered by MSCE end of May 2021 (required)
  • Non-BaP species: recommendation (even if based on 2017): CAMS-REG-AP_v4_2_emissions_year2017_REF2.1, with PM split: PM_split_for_CAMS-REG-AP_v4_2_REF2_2017.xlsx
  • Wildfires: GFAS with tpmfire species tagged as PM_wildfires in PM10 fraction (recommended)

Model Outputs

  • Surface only
  • 0.1 deg resolution, 25°W-45°E, 30°N-72°N
  • Netcdf: 1 file per species (whole period)
  • ng/m3 for BaP, µg/m3 for other species (gas/particulate species)
  • daily mean
  • BaP, PM10, PM2.5, NO2, O3 (daily max), OC, EC, PM_wildfire, NO3_25 (nitrate in PM2.5 fraction), NH4_25 (ammonium in PM2.5 fraction), SO4_25 (sulfate in PM2.5 fraction)

Time line

  • May 2021 (TFMM): Agree on experiment design
  • June 2021: all input data available (inc. emissions provided by MSC-E)
