ChAMBRe: a new atmospheric simulation chamber for aerosol modelling and bio-aerosol research

Current atmospheric aerosol research in India

Atmospheric aerosols are important from a perspective of ambient air pollution and health to humans and other biological receptors as well as for potential effects on local weather and global climate. This review attempts to account for the different research efforts of individual research groups and regulatory agencies in India on the issue of atmospheric aerosols and their effects. The review...

A new atmospheric aerosol phase equilibrium model (UHAERO): organic systems

In atmospheric aerosols, water and volatile inorganic and organic species are distributed between the gas and aerosol phases in accordance with thermodynamic equilibrium. Within an atmospheric particle, liquid and solid phases can exist at equilibrium. Models exist for computation of phase equilibria for inorganic/water mixtures typical of atmospheric aerosols; when organic species are present,...

A new inorganic atmospheric aerosol phase equilibrium model (UHAERO)

A variety of thermodynamic models have been developed to predict inorganic gas-aerosol equilibrium. To achieve computational efficiency a number of the models rely on a priori specification of the phases present in certain relative humidity regimes. Presented here is a new computational model, named UHAERO, that is both efficient and rigorously computes phase behavior without any a priori speci...

Atmospheric aerosol measurements from satellites

Satellite instruments are commonly used for measurements of aerosol optical properties in the atmosphere. In this work we use such measurements for ultra-high energy cosmic ray studies. We introduce a method of preparation of aerosol maps for the location of the Pierre Auger Observatory. For these maps the data from the Ozone Monitoring Instrument (OMI) of the Aura satellite were analyzed for t...
