Cloud Atlas

March 23, 2017. The World Meteorological Organization (WMO) has released its updated version of the International Cloud Atlas (https://www.wmocloudatlas.org) in conjunction with the World Meteorological Day.  
The Atlas is the global reference for observing and classifying clouds and other weather phenomena. For the first time, the 2017 edition will primarily be a web-based portal, allowing for much richer content and presentation easily accessible to a vast audience.
