Mapping and estimating the total living biomass and carbon in low-biomass woodlands using Landsat 8 CDR data

摘要

BackgroundA functional forest carbon measuring, reporting and verification (MRV) system to support climate change mitigation policies, such as REDD+, requires estimates of forest biomass carbon, as an input to estimate emissions. A combination of field inventory and remote sensing is expected to provide those data. By linking Landsat 8 and forest inventory data, we (1) developed linear mixed effects models for total living biomass (TLB) estimation as a function of spectral variables, (2) developed a 30 m resolution map of the total living carbon (TLC), and (3) estimated the total TLB stock of the study area. Inventory data consisted of tree measurements from 500 plots in 63 clusters in a 15,700 km² study area, in miombo woodlands of Tanzania. The Landsat 8 data comprised two climate data record images covering the inventory area.
