Arctic and boreal regions (ABRs) are experiencing rapid warming and increasingly severe wildfires, threatening their role as global carbon sinks. High quality time series maps of aboveground biomass (AGB) are key for characterizing and attributing spatiotemporal dynamics of carbon stocks in these regions. Existing maps often lack the spatial resolution or temporal coverage needed to capture the heterogeneous and dynamic nature of Arctic-boreal AGB change, therefore we address these limitations by developing annual 30-m resolution AGB density and uncertainty maps for North America ABRs from 1984-2022.
