EUCAARI-FLEXPARTTraditional Products: Retroplume Summary

Three dimensional product:

Particle plume centroid locations plotted by circles

Size is a function of number of particles in cluster

Color represents elevation

Numbers indicate days back in time

Centroid characteristics are also shown:

Altitude

% ABL – atmospheric boundary layer

%STR – stratosphere

EUCAARI-FLEXPARTTraditional Products: Potential Emissions Sensitivity

Total Column PES

Integrated over all vertical layers

Analagous to 'trajectory'

Includes 'retroplume' centroid locations

Units: ns m kg -1

EUCAARI-FLEXPARTTraditional Products: Footprint Emissions Sensitivity

Footprint PES

lowest model layer 0-100m

Units: ns kg -1

EUCAARI-FLEXPARTTraditional Products: CO, NO2, SO2 Source Contribution

Product:

we fold (i.e., multiply) the PES footprint with the emission flux densities (in unitsof kg m−2 s−1) taken from an appropriate emission inventory.

Result: potential source contribution (PSC) plot (in units of ppbv m−2)

global EDGAR 3.2 Fast Track 2000 dataset (Olivier et al., 2001) and blend this global inventory with higher-resolution regional inventories where

North American inventory from Frost et al. (2006)

European inventory from the UNECE/EMEP (United Nations Economic Commission for Europe/Cooperative Programme for Monitoring and Evaluation of Long Range Transmission of Air Pollutants in Europe) emission database (Vestreng et al., 2005).

Advantage of integrated system: comparing model results with measured time series of long-lived tracers (e.g., CO), the model’s skill can be checked. Cases where an observed event is not reproduced by the model can be identified. Likely indicates:

a source missing in the emission inventories used, or

errors in the simulated transport.

This important quality check cannot be done when using classical trajectories.
