Abstract:

Numerical weather prediction simulates aerosol abundance using climatic emission inventories due to a lack of available real-time observation. An advocation to monitor aerosol number concentration with a standardized global sensor network is defended. Analysis is done on WRF-Chem output near Dayton, Ohio after CPC data is manually inserted as WRF-Chem input at the surface. Upon confirmation of PM2.5 characterization improvement by point-observation initialization, a method of integrating PM2.5 abundance into the long-standing meteorological observation network is suggested encoding of PM2.5 number concentration in the routine meteorological aerodrome report METAR as an estimate of horizontal visibility.
