| Description |
These data describe the percent of the total grass foliage cover that is comprised of the cover from C4 grasses. It is a long-term average (2001-2021) derived from MODIS imagery. Percent values range between 10 to 95%. Data have a spatial resolution of 0.0025 decimal degrees (~250 m). No quantitative validation has been performed but only a qualitative comparison to site and mapped information. Note that this is not the foliage cover of C4 grasses, nor the relative abundance of C4 plants, but the percent of total grass foliage cover that comes from C4 plants. So, for example, if total grass foliage cover is 60% and the C4 percentage is 80%, then the C4 foliage cover would be 48% (i.e., 60% x 0.8) and the C3 grass foliage cover would be 12%.
