Cloud chart showing major tropospheric cloud types identified by standard two-letter abbreviations and grouped by altitude and form. See table below for full names and classification. The table that follows is very broad in scope much like the cloud genera template near the bottom of the article and upon which this table is partly based.
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 1890 Cloud Atlas is the first known cloud atlas and book of this title, by Hildebrandsson, Wladimir Köppen, and Georg von Neumayer. [5] It was an expensive quarto book of chromolithographs reproducing 10 color oil paintings and 12 photographs for comparison, and was designed to explore the advantages and disadvantages of photography for the scientific illustration of cloud forms.

Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases. As a result, the cloud base can vary from a very light to very-dark-gray depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer. High thin tropospheric clouds ...
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
Towards the top of the cloud, at temperatures of around −47 °C (−53 °F) to −52 °C (−62 °F), the predominant crystal types are thick, hexagonal plates and short, solid, hexagonal columns. [ 11 ] [ 12 ] These clouds commonly produce halos, and sometimes the halo is the only indication that such clouds are present. [ 13 ]
Asperitas (formerly known as Undulatus asperatus) is a cloud formation first popularized and proposed as a type of cloud in 2009 by Gavin Pretor-Pinney of the Cloud Appreciation Society. Added to the International Cloud Atlas as a supplementary feature in March 2017, it is the first cloud formation added since cirrus intortus in 1951. [2]
Cirrostratus / ˌ s ɪr oʊ ˈ s t r ɑː t ə s / is a high-altitude, very thin, generally uniform stratiform genus-type of cloud. It is made out of ice-crystals, which are pieces of frozen water. It is difficult to detect and it can make halos. These are made when the cloud takes the form of thin cirrostratus nebulosus. [1]
