- Metric Name: Total Aboveground Carbon - Data Vintage: 2021 - Unit Of Measure: Grams dry matter/m2 Identifying ecosystem carbon is essential to land managers and the Total Aboveground Carbon metric provides an estimate of the amount of existing carbon and its location on California’s landscape. The metric also serves to provide context for the other metrics used to quantify carbon sequestration. For example, instability or lack of resilience in forests with low total aboveground carbon would be of less concern than the same degree of instability in a forest that has large total aboveground carbon. Creation Method: The Center for Ecosystem Climate Solutions (CECS) DataEngine model tracks monthly carbon in multiple pools from 1986 to 2021. The carbon components are initialized with eMapR (see Additional Resources) observations for the early Landsat era; the model then runs freely based on Landsat and other observations. Disturbances and disturbance intensity are tracked annually by Landsat (see other metrics developed by CECS) and used to quantitatively transfer or combust pools. The model allocates and turns over material based on allometry scaling theory, as adjusted by observational data sets. Aboveground pools (live tree, live shrubs and dead material) are summed for September of 2021. - Credits: CECS; https://california-ecosystem-climate.solutions/ UC Irvine, CECS; https://california-ecosystem-climate.solutions/: Data disclaimer: The University of California (“UC”) makes the materials on this website available pursuant to the following disclaimers: the materials are offered “as is”; user assumes any and all risks, of any kind or amount, of using these materials; user shall use the materials only in accordance with law; user releases, waives, discharges and promises not to sue UC, its directors, officers, employees or agents, from liability from any and all claims, including the negligence of UC, resulting in personal injury (including death), accidents or illnesses, property loss, as well as any and all loss of business and/or profit in connection with user's use of the materials; and user shall indemnify and hold UC harmless from any and all claims, actions, suits, procedures, costs, expenses, damages, and liabilities, including attorney's fees, arising out of user's use of the materials and shall reimburse UC for any such incurred expenses, fees or costs.
