The Swiss-American team developed a method to gauge the effect of chemicals found in aerosols in the Earth's atmosphere and weather.

Particles of these chemicals are thought to form clouds that can be seen from the Earth and can be detected in the layer of condensation surrounding aircraft.

A member of the ETH team, Ulrich Krieger, said the new study was not aimed at improving weather forecasts. Instead, it studied long-term climatic change - such as global warming, the perforation of the ozone layer and related phenomena.

Krieger stressed that the results of the new study were only a small step towards understanding the evolution of the world's climate within the next century.

Researchers involved in the new project hope to suggest a possible outline of the world's climate in a few decades, with the help of simulations of different conditions or scenarios.
