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 .
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 ...

During the day, cirrus cloud cover drops, and during the night, it increases. [14] Based on CALIPSO satellite data, cirrus covers an average of 31% to 32% of the Earth's surface. [15] Cirrus cloud cover varies wildly by location, with some parts of the tropics reaching up to 70% cirrus cloud cover.
Cloud-cover symbols used on weather teleprinters and aviation reports in the US [6] In the early 20th century, it was common for weather maps to be hand drawn. The symbols for cloud cover on these maps, like the modern symbols, were drawn inside the circle marking the position of the weather station making the measurements.
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.

A stratocumulus cloud, occasionally called a cumulostratus, belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower height, usually below 2,000 metres (6,600 ft).
