New pictures wanted for the International Cloud Atlas

The World Meteorological Organisation (WMO) wants you to send them your cloud images.

The World Meteorological Organisation (WMO) invites the submission of images for the next edition of the International Cloud Atlas (ICA).

The Cloud Atlas was developed as a standardised reference document for operational observation systems. It is an important training tool for meteorologists, as well as for those working in aviation and at sea.  The new edition hopes to take advantage of modern digital cameras and use the power of the internet to make the document more flexible and complete.

This is where you come in.  The WMO is looking for well composed, in focus and correctly exposed photographs of the various cloud classifications and other weather phenomena, such as lightning, rainbows, snow, fog or dust. The image should also be accompanied by information on where and when the photograph was taken and a description of the weather situation. If an image is chosen it will become a new 'reference image' for professional and amateur observers around the world.

The ICA provides an authoritative, comprehensive and up-to-date source of reference which is used by a wide audience. The origins of the ICA date back to the 1800s. The most recent edition, published in 1987, contains over 200 pictures of clouds and meteors (such as precipitation types, haze, rainbows and lightning).
