Identify and discuss in details the two main methods used in measuring or determining cloud cover as an environmental aspect.

- Human observation is the traditional method of measuring cloud cover, and there is a specific measurement, the okta, that is used to describe the presence of clouds in the sky. To use oktas, the observer should look straight up at the sky and imagine it is split into eight equal wedges, or oktas, radiating out from a central point directly overhead. If one okta is fully covered and the rest are clear, the sky can be described as having one okta of cloud cover.

- The Infrared Cloud Imager (ICS) is also another method which uses a combination of satellite images and infrared imaging to provide high-resolution data that can be recorded both day and night: an improvement on methods that rely on human sight, which cannot be used at nighttime. Satellite data can also provide information about cloud cover, but this method is inferior in some ways to human observation
