Aerosols impact human and environmental health as well as global climate. In this presentation I will aim to summarize the state of the science of atmospheric chemistry research related to particulate matter (PM) and the challenges ahead. The key questions in aerosol research are linked to ...
aIt is the zone where weather phenomena and atmospheric turbulence are most marked. It contains 75% of the total molecular and gaseous mass of the atmosphere and virtually all the water vapour and aerosols. 它是区域,天气现象和大气动荡是最明显的。 它包含75%大气的总分子和气体大量和实际上所有水...
The total effective radiative forcing due to this increase in aerosols is the most uncertain component of the historical radiative forcing of Earth’s climate1. The most significant part of this aerosol related uncertainty is linked to aerosol-cloud interactions (ACI)1,2. The effect of ACI, ...
(ESI) - Ions are generated at atmospheric pressure by passing the analyte solution through a capillary (electrospray needle) that has a high potential difference (with respect to the counter electrode) applied to it (typically between 2.5 to 4 kV). This initially produces aerosols of charged ...

In this work, inorganic ammonium ions, NH4+, and carbonate ions, CO32 , are reported for the first time as catalysts for organic reactions in atmospheric aerosols and other natural environments at the Earth's surface. These reactions include the formation of C–C and C–O bonds by aldol co...
Diffuse atmospheric inputs of dust from soil erosion might be argued to adversely affect crop production and food supply, but the deposition of dust is also part of the ongoing geological process of making new soil. The issue is whether a spatial or temporal change in this cycle, or a ...
A clear barrier to transfer is the sudden shock of temperature and pressure that will occur on both exit and atmospheric reentry. Despite these harsh conditions, simulations indicate that many resistant forms of life such as bacterial endospores can survive (Mastrapa et al.,2001; Stoffler et ...
