International Cloud Atlas

The International Cloud Atlas or simply the Cloud Atlas, is a cloud atlas that was first published in 1896^[1] and has remained in print since. Its initial purposes included aiding the training of meteorologists and promoting more consistent use of vocabulary describing clouds, which were both important for early weather forecasting. The first edition featured color plates of color photographs, then still a very new technology, but noted for being expensive. Numerous later editions have been published.
