About 

The Cloud Cover Layers (CCL) product is an estimation of the cloud fraction between predefined atmospheric levels, as well as the total cloud fraction. This 5-layer product is particularly beneficial for aviation, as the classification is in Flight Layers. The 5 layers are from Above Mean Sea Level (AMSL) to Flight Layer (FL) at 5,000 ft (AMSL-FL050), from FL at 5,000 ft to 10,000 ft (FL050-FL100), from FL at 10,000 ft to 18,000 ft (FL100-FL180), from FL at 18,000 ft to 24,000 ft (FL180-FL240), and from FL at 24,000 ft to top of the atmosphere (FL240-TOA). The algorithm also produces a cloudy/clear layer flag at pixel level for each layer. The layer flag is stored using bit structure in a one byte number.

Limitations

Layer Classification Accuracy: The accuracy for classifying the correct cloud layer per the product requirements is 60%.

AWIPS Capabilities: The CAVE environment does not visualize in three dimensions, therefore the CCL produced for AWIPS has been modified from its original format.

Quality Flags: Inherited from Algorithm Working Group Cloud Height Algorithm (ACHA). Good quality flag mask (DQF=0) is used for each cloud layer field.

Technique: CCL may be used to determine areas of cloud growth and likelihood of precipitation. The product is also useful for assessing Ceiling & Visibility, and composing Terminal Aerodrome Forecasts (TAFs) at various altitudes.
