Make Cloud cover and cloud type observations at solar or astronomical noon, when the sun is highest in the sky, and at the same time that you make your temperature measurements. These clouds are made up of mostly water. Low clouds mostly contain water but can also be made up of snow and ice particles. The Cloud Catalog and complete the Clouds Types Section of your Unit 1C Questions 2. Another Cloud Quiz 4.
Students report the amount of cloud cover present.
The student's own eyes. Cloud cover can sometimes be a little difficult to estimate because of our limited view of the sky. Study this picture and compare the gaps between the clouds that the student sees and what they really are. Sky is cloudless or the cloud coverage averages less than one tenth. Five tenths to nine tenths of the sky is covered by clouds.
