lossyearYear of gross forest cover loss event. Forest loss during the study period, defined as a stand-replacement disturbance, or a change from a forest to non-forest state. Encoded as either 0 (no loss) or else a value in the range 1–20, representing loss detected primarily in the y...
ForestLandsatGlobalSamplingThe Global Land Cover Facility (GLCF) global forest-cover and -change dataset is a multi-temporal depiction of long-term (multi-decadal), global forest dynamics at high (30-m) resolution. Based on per-pixel estimates of percentage tree cover and their associated ...
The GLCF global forest-cover and -change dataset is a multi-temporal depiction of long-term (multi-decadal), global forest dynamics at high (i.e., 30-m) resolution, or pixel-size. Based on per-pixel estimates of tree cover and their associated uncertainty (Sexton, J. O., et al., 20...
Global forest cover maps High-resolution (30 m) global forest cover data for 2000 and 2020 were obtained from the global land cover and land use (GLCLU) change dataset51. The GLULC forest cover data defines a pixel with tree height ≥5 m at the Landsat pixel scale as a forest pi...

The impacts of enhanced nitrogen (N) deposition on the global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key...
Globe Land30 is the world's first 30-meter resolution global-land cover dataset developed by China under the support of 863 key project. It contains ten major land cover classes: cultivated land, forest, grassland, shrub-land, wetland, water bodies, tundra, artificial surfaces, bare land and...
