Atmospheric Chemistry

Main Researcher: Josep Maria Anglada

The atmosphere is like a huge living organism. The Earth atmosphere is fed by sun radiation and by the release of enormous amounts of matter from the earth surface, including both biogenic and anthropogenic sources.

Atmospheric Chemistry

The matter emitted to the atmosphere is oxidized mainly by OH and by O3 in day-time, and by NO3 in night-time, and the products of this oxidation are organic and inorganic acids, aldehydes, carbon dioxide, carbon monoxide or highly reactive radicals.

These oxidation processes dominate the chemistry of air pollution, causing a direct effect on human health. In addition, species like carbon dioxide, methane or ozone are greenhouse gases, having a direct impact on climate change.

Many products of the oxidation of atmospheric species can either form aerosols or be taken up by clouds and be eliminated by rain.

Our research focusses on:
Reactions initiated by Ozone and Carbonyl oxides.
Reactions initiated by radicals (HOx, NOx).
Effects of water vapor and other trace gases in atmospheric reactions.
Reactivity at the air-water interface.
