Effects of long-range aerosol transport on the microphysical properties of low-level liquid clouds in the Arctic
The properties of low-level liquid clouds in the Arctic can be altered by long-range pollution transport to the region. Satellite, tracer transport model, and meteorological data sets are used here to determine a net aerosol–cloud interaction (ACInet) parameter that expresses the ratio of relative c...
