Edgar Degas, J. M. W. Turner and other painters captured centuries of atmospheric records as

they decorated canvases with sunset scenes.

Greek scientists worked with an artist to confirm that the ratio of red to green in sunset

painting, both old and new, increased when particles filled the air, such as after major volcanic

eruption(火山喷发) or dust storms. The atmospheric physicists also found a gradual shift in artistic

sunset over centuries, possibly due to ever-increasing air pollution during the Industrial

Revolution.

An earlier study, led by atmospheric physicist Christos Zerefos of the Academy of Athens in

Greece, discovered that the amount of red relative to green in sunset descriptions increased after

eruptions, including Tambora, Indonesia in 1815, Coseguina, Nicaragua in 1835 and Krakatau,

Indonesia in 1883.

Zerefos’ team analyzed 554 paintings created between 1550 and 1990. For up to three years

after eruptions, sunsets reddened as sunlight bounced off dust and gas from the volcanoes. The

latest study, also by Zerefos, used improved scanning and analysis techniques to confirm the earlier

results.

A modern painter, Panayiotis Tetsis, unknowingly repeated the artistic atmospheric

observations of classical masters. In the artists’ description of sunsets light over the Greek island of

Hydra, the color ratio shifted towards red in paintings done both before (June 19, 2010) and after

(June 20, 2010) a dust cloud from Sahara Desert filtered the sunset’s light.

Zerefos’ team connected the timing of classical paintings’ red shift to other records of the

atmosphere trapped in ice cores from Greenland, in the recent study published in Atmospheric

Chemistry and Physics. The ice cores recorded spikes(尖刺) in sulfur-containing chemicals likely

from volcanoes. These spikes corresponded in time to artists’ increasingly dark red sunsets.

The comparison of ice and art also revealed a slow shift in the coloring of the sunset. As the
