Circumpolar Boreal Forest Aboveground Biomass Density, V3

This dataset provides estimates of aboveground dry woody biomass density (AGBD) for high northern latitude forests at a 30-m spatial resolution for the year 2020, accounting for >30% of global forest area. The estimates were derived with state-of-the-art earth observation datasets collected from space, including lidar observations from NASA's ICESat-2 and imagery from NASA's Harmonized Landsat/Sentinel-2 project. They are designed for circumpolar boreal-wide mapping from local to global scales and provide the northern component of global forest structure estimates, to which complementary estimates from NASA's Global Ecosystem Dynamics Investigation (GEDI) mission contribute temperate and tropical portions. The AGBD predictions cover the extent of high latitude boreal forests and shrublands, and while they extend southward outside the boreal domain nominally to ~50 degrees N they are intended to contribute to global estimates northward from 51.6 degrees N. The data are provided in cloud optimized GeoTIFF, parquet, and GeoPackage formats.
