Abstract The Northern Aerosol Regional Climate Model (NARCM) was used to construct a 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960–2003. Comparisons with available ground observations Total Ozone Mapping Spectrometer (TOMS) Index (AI) measurements verified that NARCM captured most the climatological characteristics spatial temporal distributions, as well interannual daily variations those 44 yr....
Abstract A 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960–2003 was simulated with the Northern Aerosol Regional Climate Model (NARCM).

We identified 270 events pulses 254 1 January 2001 to 31 March 2009. found that poloidal toroidal oscillate similar manner of phase near 06:00 local time (LT) 18:00 LT, but...
Size-resolved aerosol number and mass concentrations the mixing ratios of O3 various trace gases were continuously measured at an urban station before during Beijing Olympic Paralympic Games (5 June to 22 September, 2008). 23 new particle formation (NPF) events identified; these usually associated with changes in wind direction and/or rising gas-phase precursors or after precipitation events. Most NPF started morning continued noon as particles nucleation mode grew into Aitken mode. From...

Based on two-dimensional probability density function diagnosis model for emissions, study extends pollution PLAM regional intensity. The results show that combining influence regular conditions factors together parameterization...
