Researchers from the University of Utah and NASA have released new datasets and a meta-analysis to improve the accuracy of carbon biomass measurements in Arctic and boreal regions. The work addresses the inconsistency between existing satellite datasets, providing a guide for policymakers to choose the most reliable data for national carbon budgets. A new high-resolution biomass map tracking ecological changes since 1984 allows scientists to detect carbon shifts at a 30-meter resolution. This detail is critical for determining whether northern forests remain carbon sinks or have become carbon sources due to intensifying wildfires and drought.
