SOSA – a new model to simulate the concentrations of organic vapours and sulphuric acid inside the ABL – Part 1: Model description and initial evaluation
SOSA organic vapours sulphuric acid the ABL initial evaluation
2011/1/18
Chemistry in the atmospheric boundary layer (ABL) is controlled by complex processes of surface fluxes, flow, turbulent transport, and chemical reactions. We present a new model SOSA (model to simulat...
Inter-community variability in total particle number concentrations in the eastern Los Angeles air basin
particle number the eastern Los Angeles air basin
2010/12/20
Ultrafine Particles (UFP) can display sharp gradients in their number concentrations in urban environment due to their transient nature and rapid atmospheric processing. The ability of using air pollu...
