Tier 1 data are the IPCC default values for forest carbon stocks, whereas Tier 2 indicates country-specific data (see Table 4). Total forest carbon (C) was estimated from aboveground live biomass (AGLB) using conversion factors from each source for aboveground dead biomass (AGDB) and below-ground biomass (BGB) as a percentage of AGLB.
¹ Average total carbon in forest biomass for tropical rainforest South America (SA), Brazilian Amazon (BA), or Mato Grosso (MT).
² Tier 2 biomass data products were divided between regional or state-wide average values (Tier 2.a) and spatially-explicit maps of forest biomass (Tier 2.m).
³ As reported by [80]
⁴ The RADAMBRASIL floristic inventory (DPNM, 1973-1983).
⁵ Nogueira et al (2009) applied additional correction factors for AGLB in dense (10.5%) and non-dense (15.7%) forest types. These factors were also included in the Imazon product.
