Background

Main motivation: improve the modelling of Black Carbon (Tagged Elemental Carbon), SOA (Condensables), and BaP

Take stock of (i) Developments in emission inventories (LRTAP BC, condensables) and (ii) Winter 2017/2018 field campaign (EMEP/ACTRIS/COLOSSAL)

Modelling experiment

Assess the impact of a more consistent emission inventory for wood burning

A: CAMS-REG-AP_v2.2.1_2015_REF1: EMEP National Totals + TNO Spatialisation

B: CAMS-REG-AP_v2.2.1_2015_REF2: Same as A but including Condensable for Small Combustion in primary PM (independently from EMEP national totals)

Compare with the EMEP reference inventory (main difference compared to A regards spatialisation proxies)

C: EMEP 0.1 official country inventories

Test the LRTAP Black Carbon inventory (only available for 2017)

D: Same as C + BC modelling

Test the LRTAP BaP inventory

E: Same as C + BaP

Note: C/D/E can be part of the same model run

PM Splits (EC, OC, SO4, Na, OthMin in PM10 and PM2.5, note the different versions for REF1&REF2): PM_split_for_CAMS-REG-AP_v2_2_1_rev_20190326_REF1_2015.xlsx, PM_split_for_CAMS-REG-AP_v2_2_1_rev_20190326_REF2_2015.xlsx

Wood Burning / Fossil Fuel Share in PM10 and PM2.5 emissions (note the different versions for REF1&REF2): Share_biofuels_in_PM_small_combustion_REF1_2015.csv, Share_biofuels_in_PM_small_combustion_REF2_2015.csv

EC_wb is defined as the wood burning share of EC emissions in the PM2.5 fraction. It is computed from the national/sector PM2.5 emissions, modulated by the GNFR_Sector/C share of EC_fine and the share of biofuel for a given country

EC_ff is defined as the fossil fuel share of EC emissions in the PM2.5 fraction. It includes all the remaining EC_fine

Splits only available for coarse/fine (above/below 2.5µm), models apply their own splits below 1µm

Temporal variations: not prescribed (degree days or monthly climatologies)

Model Outputs

Surface only

CAMS grib (for CAMS models) or netcdf: 1 file per species (whole period)

Units: kg/m3 for the grib files, µg/m3 for the netcdf files (gas/particualte species)

Species: (grib codes in brackets for models using grib format, when available)

Please deliver as many species as possible, the priority is on PM10, PM2.5, ECff_2.5, ECwb_2.5. We note that PM1 is not available in emissions, and therefore in many models

PM10 (40008), PM2.5 (40009), PM1 (62078), NO2 (5), O3 (0),

PM Species in PM2.5 fraction: ECff_25 (62097), ECwb_25 (62098), POA_25 (62011), SOA_25 (62012), NO3_25 (13), NH4_25 (10), SO4_25 (22), OPPM_25 (any other primary PM, 62094)

PM Species in PM1 fraction: ECff_1 (62089), ECwb_1 (62091), POA_1 (62087), SOA_1 (62085), NO3_1 (62079), NH4_1 (62081), SO4_1 (62083), OPPM_1 (62093)

PM Species in PM10 fraction: ECff_10 (62090), ECwb_10 (62092), POA_10 (62088), SOA_10 (62086), NO3_10 (62080), NH4_10 (62082), SO4_10 (62084), OPPM_10 (62095)
