The cloud cover fraction represents the proportion of a given area covered by clouds. According to provided information, cloud fraction is the percentage of each pixel in satellite imagery or each grid box in a weather or climate model that is covered with clouds. A cloud fraction ranges from 0 to 1, where a cloud fraction of 1 indicates complete cloud cover, and 0 indicates a completely clear sky.
Here's a breakdown:
- Definition: Cloud cover fraction is a measure of how much of a particular area is covered by clouds.
- Range: The value ranges from 0 to 1. This can also be represented as a percentage, from 0% to 100%.
- Interpretation:
- 0 (or 0%) signifies a completely clear sky with no clouds.
- 1 (or 100%) signifies that the area is completely covered by clouds.
- Values in between represent partial cloud cover. For example, 0.5 (or 50%) indicates that half of the area is covered by clouds.
- Application: Cloud fraction is used in various fields, including:
- Satellite imagery analysis.
- Weather forecasting.
- Climate modeling.
