Real-time measurement of water-insoluble aerosol in the chamonix and maurienne valleys of alpine france

摘要

The solubility of atmospheric particulars matter influences the hygroscopic growth of particles and thus aerosol chemistry and light extinction properties.Aerosol solubility also affects the ability of particles to create cloud droplets and therefore influences cloud formation and lifetime (and consequently,the radiation balance of the earth).In addition,the dry deposition of insoluble particles to leaf surfaces is believed to negatively influence plant growth and thus CO_2 uptake.The aerosol water-insoluble fraction is also thought to adversely affect human health.Unfortunately,to date,very little scientific information has been gathered concerning the quantity of insoluble particulate matter present in the atmosphere.
