Journal ArticleDOI
Distribution of Aboveground Live Biomass in the Amazon Basin
TL;DR: In this article, a decision tree approach was used to develop the spatial distribution of aboveground live biomass (AGLB) for seven distinct biomass classes of lowland old-growth forests with more than 80% accuracy.
Journal ArticleDOI
Post-drought decline of the Amazon carbon sink.
Yan Yang,Sassan Saatchi,Sassan Saatchi,Liang Xu,Liang Xu,Y. Yu,Sungho Choi,Nathan Phillips,Robert E. Kennedy,Michael Keller,Michael Keller,Yuri Knyazikhin,Ranga B. Myneni +12 more
TL;DR: The long-term legacy of these droughts with persistent loss of carbon stocks after the 2005 drought is shown, leading to a significant positive climate feedback and exacerbating warming trends.
Journal ArticleDOI
Sensitivity of L-Band SAR Backscatter to Aboveground Biomass of Global Forests
Y. Yu,Sassan Saatchi +1 more
TL;DR: The results demonstrate that L-Band backscatter relations to AGB can be significantly different depending on forest types and environmental effects, requiring multiple algorithms to map AGB from time series of satellite radar observations globally.
Journal ArticleDOI
Estimation of forest aboveground biomass in California using canopy height and leaf area index estimated from satellite data
G. Zhang,Sanmay Ganguly,Ramakrishna R. Nemani,Michael A. White,Cristina Milesi,Hirofumi Hashimoto,Weile Wang,Sassan Saatchi,Y. Yu,Ranga B. Myneni +9 more
TL;DR: In this paper, a parametric model that combines high-resolution estimates of leaf area index (LAI) from the Landsat Thematic Mapper sensor and canopy maximum height from the Geoscience Laser Altimeter System (GLAS) sensor onboard ICESat, the Ice, Cloud, and land Elevation Satellite is presented.
Journal ArticleDOI

TL;DR: In this paper, the authors developed spatially explicit estimates of carbon stock changes of live woody biomass from 2000 to 2019 using measurements from ground, air, and space, and showed that live biomass has removed 4.9 to 5.5 PgC year−1 from the atmosphere, offsetting 4.6 ± 0.1 pgC of gross emissions from disturbances and adding substantially (0.23 to 0.88 pgc year− 1) to the global carbon stocks.
