This dataset provides gridded estimates of aboveground biomass (AGB) for live dry woody vegetation density in the form of both stock for the baseline year 2003 and annual change in stock from 2003 to 2016. Data are at a spatial resolution of approximately 500 m (463.31 m; 21.47 ha) for three geographies: the biogeographical limit of the Amazon Basin, the country of Mexico, and a Pantropical belt from 40 degrees North to 30 degrees South latitudes. Estimates were derived from a multi-step modeling approach that combined field measurements with co-located LiDAR data from NASA ICESat Geoscience L...本数据集提供了活体干燥木本植被密度的地上生物量（aboveground biomass，AGB）栅格化估算结果，涵盖2003年基准年的生物量存量数据，以及2003年至2016年间的生物量存量年变化量。数据空间分辨率约为500米（实际精度为463.31米，对应21.47公顷），覆盖三类地理区域：亚马孙流域的生物地理边界、墨西哥全境，以及纬度范围为北纬40°至南纬30°的泛热带地带。该估算结果基于多步建模方法生成，将野外实测数据与美国国家航空航天局（NASA）ICESat地球科学激光雷达（LiDAR）的协同定位数据相结合……
