FLEXPART model tools for black carbon and mineral dust for NASA’s ARCSIX campaign in 2024

FLEXPART version 10.4 (Pisso et al., https://doi.org/10.5194/gmd-12-4955-2019) in backward mode simulated transport of black carbon (BC) and mineral dust along flight tracks of three different airplanes during the ARCSIX campaign in High Arctic (north of Greenland.

For BC, the following products are given, which are FLEXPART model results coupled with emissions inventories for BC as described below:
• Footprint: Footprint emissions sensitivity showing the probability of any release occurring in any grid-cell to reach the receptor (flight point) for 30 days particle tracking. In newer versions of the product, the average column trajectory of the footprint is plotted on each map as a function of the height of the plume center (gray colorbar on the right). Each colored circle represents each day backward in time from the release. In addition, there is a timeseries plot under the map showing the plume height versus time backward in time (black line) and on the right secondary axes, the percentage of particles in the planetary boundary layer (PBL) in magenta color and the percentage of particles in the stratosphere (STRA) in blue. Each circle represents days backward from the release date and time. Data are given in gif and netCDF format.
• DOM BC: Modelled contribution to surface black carbon (BC) from residential and commercial sector plotted on a map (three projections). DOM includes emissions from combustion in heating and cooking stoves and boilers in households and public and commercial buildings (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• ENE BC: Modelled contribution to surface black carbon (BC) from energy production sector plotted on a map (three projections). ENE includes emissions from combustion processes in power plants and generators (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• IND BC: Modelled contribution to surface black carbon (BC) from industrial combustion plotted on a map (three projections). IND includes emissions from industrial boilers and industrial production processes (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• FLR BC: Modelled contribution to surface black carbon (BC) from gas flaring plotted on a map (three projections). FLR includes emissions from oil and gas facilities (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• SHP BC: Modelled contribution to surface black carbon (BC) from shipping activities in in-land waters plotted on a map (three projections) (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• WST BC: Modelled contribution to surface black carbon (BC) from waste treatment and disposal sector plotted on a map (three projections). WST resembles emissions from waste incineration and treatment (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• TRA BC: Modelled contribution to surface black carbon (BC) from transportation sector plotted on a map (three projections). TRA includes emissions from all land-based transport of goods, animals and persons on road networks and off-road activities (ECLIPSEv6, Klimont et al., https://doi.org/10.5194/acp-17-8681-2017). Data are given in gif and netCDF format.
• Wildfire BC: Modelled contribution to surface black carbon (BC) from open biomass burning (excluding agricultural fires) plotted on a map (three projections) (GFEDv4, Giglio et al., https://doi.org/10.1002/jgrg.20042). Data are given in gif and netCDF format.
• Total BC: The sum of the BC contributions.
• Source Spec: Timeseries plot of modelled concentrations in 3h resolution showing the contribution of each source (DOM BC, ENE BC, IND BC, FLR BC, SHP BC, WST BC, TRA BC, Fire BC) to surface BC. Data are given in gif and ascii format.
• Continent Spec: Timeseries plot of modelled concentrations in 3h resolution showing the continental contribution (OCE: Ocean, GNL: Greenland, SA: South America, CA: Central America, NA: North America, AFR: Africa, EUR: Europe, RUS: Russia, ASI: Asia excluding Russian part, AUS: Australia) to surface BC. Data are given in gif and ascii format.
• Age Spec: Timeseries plot of modelled concentrations in 3h resolution showing the age contribution of the plume to surface BC. The latter shows how “fresh” or “old” the air arriving at the receptor is. Data are given in gif and ascii format.

For mineral dust, the following products are given, which are FLEXPART model results coupled with emissions inventories for dust as described below:
• Footprint: Same as for BC, but including 10 different size fractions for fine and coarse mode (DU01 to DU10), namely 0.04, 0.22, 0.71, 1.304, 2.057, 3.53, 6.1, 8.63, 12.2, 17.32 um. Data are given in gif and netCDF format.
• Continent Spec: Timeseries plot of modelled concentrations in 3h resolution showing the continental contribution (OCE: Ocean, GNL: Greenland, SA: South America, CA: Central America, NA: North America, AFR: Africa, EUR: Europe, RUS: Russia, ASI: Asia excluding Russian part, AUS: Australia) to surface dust. Data are given in gif and ascii format.
• Age Spec: Timeseries plot of modelled concentrations in 3h resolution showing the age contribution of the plume to surface dust. The latter shows how "fresh" or "old" the air arriving at the receptor is. Data are given in gif and ascii format.
• Total Dust: Dust emissions were simulated using the FLEXDUST model (Groot Zwaaftink et al. https://doi.org/10.5194/acp-17-10865-2017; Wittmann et al. https://doi.org/10.5194/tc-11-741-2017; Groot Zwaaftink et al. https://doi.org/10.1002/2016JD025482). Here, we include modelled contribution to surface dust on a map. Data are given in gif and netCDF format.
