Title: Aboveground biomass carbon over the Amazon for 2010-2020.
Description: The Amazon rainforest is crucial for the global carbon cycle, yet annual changes in its aboveground biomass carbon (AGC) stock remain highly uncertain due to the lack of fine-resolution and temporally consistent information. The current dataset contains reconstructed maps of annual AGC change at a ~100m spatial resolution, resulting from the disaggregation of low-frequency passive L-band microwave data over 2010-2020. They show that the Amazon lost −0.37 ± 0.17 PgC, with gains by undisturbed (0.33 ± 0.13 PgC) and secondary forest growth (0.33 ± 0.05 PgC) outweighed by losses by deforestation (−0.55 ± 0.04 PgC), degradation (−0.42 ± 0.08 PgC), and agricultural areas (−0.06 ± 0.03 PgC).
Spatial coverage: The Amazon basin, Brazil
Pixel size: 0.000888° (~100m at the Equator)
Temporal coverage: 2010-2022
Projection: WGS84

Note: The expected value of AGB each pixel follows a log-normal distribution with parameters μ and σ. Files "3out_mean_{year}.tif" are the median of this distribution [i.e., exp(μ)]. The median can be used as a point estimate of the expected aboveground biomass carbon (AGC) stock (in MgC/ha) over the Amazon.
