Canopy Chlorophyll Content Index (CCCI)
Canopy Chlorophyll Content Index (CCCI)
| Datapoint | ccci |
|---|---|
| Name | Canopy Chlorophyll Content Index (CCCI) |
| Description | The Canopy Chlorophyll Content Index (CCCI) is a vegetation index that combines information from both red-edge and near-infrared (NIR) spectral bands to assess the chlorophyll content of plant canopies. It is particularly useful in precision agriculture for monitoring crop health, diagnosing nutrient deficiencies, and optimizing fertilization strategies. CCCI is sensitive to variations in chlorophyll content, making it an effective tool for managing crop nutrition and improving yield prediction. |
| Formula | CCCI = [(NDRE - NDRE_min) / (NDRE_max - NDRE_min)] × [(NDVI - NDVI_min) / (NDVI_max - NDVI_min)], Where: NDRE = (NIR - Red Edge) / (NIR + Red Edge) |
| Data interpretation | Higher values generally indicate higher chlorophyll content in plant canopies. Lower values suggest lower chlorophyll content or other factors affecting vegetation health. |
| Data format | float with range from -1.00 to 1.00 |
Common uses include:
- Precision agriculture: To monitor crop chlorophyll content, assess nutrient levels, and optimize fertilization. It helps in diagnosing nutrient deficiencies, improving yield predictions, and managing crop variability within fields.
- CCCI is also used in research studies focusing on plant physiology and stress responses.
