The International Cloud Atlas - the global reference for identifying clouds – has been translated into Arabic, Chinese, French, Russian and Spanish. The digitized Atlas has been available in English since 2017, replacing a hard cover publication which was first issued in the late 19th century. The web-based portal contains hundreds of images of clouds and phenomena like rainbows, halos, snow devils and hailstones submitted by meteorologists, photographers and cloud lovers from around the globe.
