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.

MODIS Vegetation Continuous Fields (MOD44B) provides global sub-pixel estimates of three land cover components (percent tree cover; percent non-tree vegetation; and percent non-vegetated) at 250 m spatial resolution. A global water mask (MOD44W) is also included as an embedded ancillary layer.
