+## General description
+
+Aboveground carbon density quantifies the expected density of carbon stored in woody biomass across the
+landscape, measured in mass per area (megagrams of carbon per hectare). It is not a direct estimate of the total
+carbon in that pixel, as the spatial resolution of each pixel is less than one hectare. To estimate total carbon in a
+pixel, users should normalize these values to account for the size of each pixel, or average the density values to 1
+hectare in an equal area projection.
+
+The data layer has four bands:
+
+- **Aboveground Carbon Density** quantifies the density of carbon stored in woody vegetation,
+  primarily trees and shrubs. Grassland, herbaceous, and soil carbon stocks are not quantified.
+- **Lower prediction bound (5th percentile)** of the 90% prediction interval for model predictions at each pixel.
+- **Upper prediction bound (95th percentile)** of the 90% prediction interval for model predictions at each pixel.

+## General description
+
+Canopy cover quantifies the percentage of area occupied by trees within a
+pixel, where a tree is defined as vegetation 5 meters or taller. This metric will be most sensitive to tree clearing
+events like timber harvest or deforestation, but is also sensitive to seasonal leaf-on variation and to drought.
+
+The data layer has four bands:
+
+- **Canopy Cover** quantifies the horizontal area occupied by tree canopies that are > 5m tall.
+- **Lower prediction bound (5th percentile)** of the 90% prediction interval for model predictions at each pixel.
+- **Upper prediction bound (95th percentile)** of the 90% prediction interval for model predictions at each pixel.
