Vegetation Continuous Fields
Proportional estimates of cover are developed from global training data derived using high-resolution imagery. The training data and phenological metrics are used with a regression tree to derive percent cover globally. The model is then used to estimate areal proportions of life form, leaf type, and leaf longevity. The current V004 collection of the yearly MODIS Vegetation Continuous Fields (VCF) product contains only percent tree cover, with the other layers to follow in later releases. The data layers in the VCF product are generated on an annual basis from monthly composites of 500-m Surface Reflectance data. Compositing is based on the second darkest albedo to remove clouds and cloud shadow.
