Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

Mineral dust aerosol is one of the major types of aerosol present in the troposphere. The
molecular level interactions of water vapor with mineral dust are of global significance …

Mineral dust particles suspended in the atmosphere span more than three orders of
magnitude in diameter, from< 0.1 µm to more than 100 µm. This wide size range makes dust …

Haze in China has been increasing in frequency of occurrence as well as the area of the
affected region. Here, we report on a new mechanism of haze formation, in which …

A regional haze with daily PM2. 5 (fine particulate matters with diameters less than 2.5 µm)
exceeding 500 µg/m3 lasted for several days in January 2013 over North China, offering an …

Satellite-based retrievals of tropospheric NO 2 columns are widely used to infer NO x (≡
NO+ NO 2) emissions. These retrievals rely on model information for the vertical distribution …

Air quality models have not been able to reproduce the magnitude of the observed
concentrations of fine particulate matter (PM 2.5) during wintertime Chinese haze events …

This paper presents a review of recently acquired knowledge on the physico-chemical
properties of mineral dust from Africa and Asia based on data presented and discussed …

Southeast Asia has a very high population density and is on a fast track to economic
development, with most of the growth in electricity demand currently projected to be met by …

We describe the Harvard–NASA Emission Component version 1.0 (HEMCO), a stand-alone
software component for computing emissions in global atmospheric models. HEMCO …
