A cyanometer is an instrument for measuring the blueness of the sky. It was invented in 1789 by scientist Horace-Bénédict de Saussure who correctly surmised that blueness was dependent on the amount of water vapor suspended in the atmosphere.

In Salt Lake City winters, warm air traps cold air in the valley like a lid, called an inversion. Not only is air trapped, but air pollution including the dangerous PM2.5 particles. During winter months the air is so brown, the beautiful mountains disappear. The Salt Lake City Cyanometer is a tool you can wear that helps measure the intensity of the smog-colored sky.
