Aerosols and PM

Particular matter (PM), or aerosol, is the general term used for a mixture of solid particles and liquid droplets found in the atmosphere. Natural (dust and volcanic ash) and anthropogenic aerosols (biomass burning smoke, industrial pollution) influence cloud properties, alter the radiation budget of the earth-atmosphere system, affect atmospheric circulation patterns and cause changes in surface temperature and precipitation, and monitoring them is important.
