Aboveground Carbon Turnover Time and Residency Time

The average lifetime of aboveground live and dead carbon in years. Locations where the lifetime or turnover time is longer have more carbon in more stable pools, such as large trees or large coarse woody debris. Locations where the lifetime or turnover time is shorter have more carbon in labile pools, such as live or dead leaves.

creation_method Calculated from the ratio of total aboveground carbon and annual decomposition. Aboveground carbon and annual decomposition are both calculated for 2020 from a Landsat-driven pools and fluxes model, as described for the total aboveground carbon product. Aboveground turnover time does not currently account for carbon losses and removals with combustion or harvest. CECS data that reflect landscape changes resulting from disturbances require 6 to 12 months of Landsat observations **after a given year that included major disturbances (such as a high severity wildfire)** to fully quantify that disturbance. CECS data that reflect disturbance, such as this data layer, are therefore available **through water year 2020 (i.e. through September 2020)**.
