Application of the variability-size relationship to atmospheric aerosol studies: estimating aerosol lifetimes and ages
variability-size relationship atmospheric aerosol estimating aerosol lifetimes ages
2009/3/12
Aerosol variability is examined as function of particle size for data collected over the Northern Indian Ocean in February 1999 as part of the INDOEX experiment. It was found that for particles believ...
