In order to obtain the source/sink functions for atmospheric particulateslocated on the planetary surface or elevated in the atmosphere; directaerosol emission measurements are required. For this purpose, theperformance of an airborne aerosol flux measurement system with an improved3-kilometer (km) spatial resolution is evaluated in this study. Eddycovariance method was used in flux calculations. A footprint for airborneflux sampling with the increased resolution becomes comparable in area tothe footprint for tower sampling (with the footprint length being 2 to 10 km). The improvement in spatial resolution allows the quantification ofemission rates from individual sources located several kilometers apart suchas highway segments, city blocks, and remote and industrial areas. Theadvantage is a moving platform that allows scanning of aerosol emissions ordepositions over regional geographic scales. Airborne flux measurements withthe improved spatial resolution were conducted in various environmentsranging from clean to partly polluted marine to polluted continentalenvironment with low (<500 m) mixed boundary layer heights. The upwardand downward fluxes from the clean marine environment were smaller than0.5×106 particles m−2 s−1 in absolute value. The effectiveemissions measured from a ship plume ranged from 2×108 to3×108 m−2 s−1, and effective fluxes measured crossing cities plumes withpopulations of 10 000 to 12 000 inhabitants were in the range of 2×108to 3×108 m−2 s−1. Correlations between heat and aerosol fluxesare evaluated
