  • Meta-analysis of North American Arctic and boreal aboveground biomass datasets

    Open AccessWanwan Liang, Kirsten Bauck et al.ARTICLEEnvironmental Research Letters2026

    The North American arctic and boreal regions (ABRs) are rapidly warming and experiencing intensifying disturbances. Accurately quantifying aboveground biomass (AGB) is critical for understanding the impacts of these changes on the carbon cycle and for designing climate change mitigation strategies. Several AGB maps have been developed for the North American ABRs, including recent contributions from National Aeronautics and Space Administration’s …

  • Characterizing and communicating uncertainty

    Open AccessRobert E Kennedy, Sylvia Serbin et al.ARTICLEEnvironmental Research Letters2024

    Navigating uncertainty is a critical challenge in all fields of science, especially when translating knowledge into real-world policies or management decisions. However, the wide variance in concepts and definitions of uncertainty across scientific fields hinders effective communication. As a microcosm of diverse fields within Earth Science, NASA’s Carbon Monitoring System (CMS) provides a useful crucible in which to identify cross-cutting concep…

  • Estimating aboveground biomass density using hybrid statistical inference with Gedi lidar data and Paraguay’s national forest inventory

    Open AccessEric L Bullock, SEAN P HEALEY et al.ARTICLEEnvironmental Research Letters2023

    Forests are widely recognized as critical to combating climate change due to their ability to sequester and store carbon in the form of biomass. In recent years, the combined use of data from ground-based forest inventories and remotely sensed data from light detection and ranging (lidar) has proven useful for large-scale assessment of forest biomass, but airborne lidar is expensive and data acquisition is infeasible for many countries. By contra…

  • Impact of leaf phenology on estimates of aboveground biomass density in a deciduous broadleaf forest from simulated Gedi lidar

    Open AccessK C Cushman, John Armston et al.ARTICLEEnvironmental Research Letters2023

    The Global Ecosystem Dynamics Investigation (GEDI) is a waveform lidar instrument on the International Space Station used to estimate aboveground biomass density (AGBD) in temperate and tropical forests. Algorithms to predict footprint AGBD from GEDI relative height (RH) metrics were developed from simulated waveforms with leaf-on (growing season) conditions. Leaf-off GEDI data with lower canopy cover are expected to have shorter RH metrics, and …

  • On the Nasa Gedi and ESA CCI biomass maps

    Open AccessNeha Hunka, Maurizio Santoro et al.ARTICLEEnvironmental Research Letters2023

    Earth Observation data are uniquely positioned to estimate forest aboveground biomass density (AGBD) in accordance with the United Nations Framework Convention on Climate Change (UNFCCC) principles of ‘transparency, accuracy, completeness, consistency and comparability’. However, the use of space-based AGBD maps for national-level reporting to the UNFCCC is nearly non-existent as of 2023, the end of the first global stocktake (GST). We conduct an…

  • Seasonal flooding provides limitations and opportunities for ecosystem carbon accounting from space

  • Gedi launches a new era of biomass inference from space

    Open AccessRalph Dubayah, John Armston et al.ARTICLEEnvironmental Research Letters2022

    Accurate estimation of aboveground forest biomass stocks is required to assess the impacts of land use changes such as deforestation and subsequent regrowth on concentrations of atmospheric CO 2 . The Global Ecosystem Dynamics Investigation (GEDI) is a lidar mission launched by NASA to the International Space Station in 2018. GEDI was specifically designed to retrieve vegetation structure within a novel, theoretical sampling design that explicitl…

  • Assessing protected area’s carbon stocks and ecological structure at regional-scale using Gedi lidar

    Open AccessMengyu Liang, Mariano Gonzalez-Roglich et al.ARTICLEGlobal Environmental Change2022Referências: 3

    Protected areas (PAs) serve as a critical strategy for protecting natural resources, conserving biodiversity, and mitigating climate change. While there is a critical need to guide area-based conservation efforts, a systematic assessment of PA effectiveness for storing carbon stocks has not been possible due to the lack of globally consistent forest biomass data. In this study, we present a new methodology utilizing forest structural information …

  • The connection between forest degradation and urban energy demand in sub-Saharan Africa

    Open AccessF Sedano, Sá Nogueira Lisboa et al.ARTICLEEnvironmental Research Letters2021

    Charcoal is a key energy source for urban households in sub-Saharan Africa and charcoal production is the main cause of forest degradation across the region. We used multitemporal high-resolution remote sensing optical imagery to quantify the extent and intensity of forest degradation associated with charcoal production and its impact on forest carbon stocks for the main supplying area of an African capital. This analysis documents the advance of…

  • Towards mapping the diversity of canopy structure from space with Gedi

    Open AccessFabian Schneider, António Ferraz et al.ARTICLEEnvironmental Research Letters2020

    Plant biodiversity supports life on Earth and provides a range of important ecosystem services, but is under severe pressure by global change. Structural diversity plays a crucial role for carbon, water and energy cycles and animal habitats. However, it is very difficult to map and monitor over large areas, limiting our ability to assess the status of biodiversity and predict change. NASA’s Global Ecosystem Dynamics Investigation (GEDI) provides …

  • Statistical properties of hybrid estimators proposed for Gedi—Nasa’s global ecosystem dynamics investigation

    Open AccessPaul L Patterson, SEAN P HEALEY et al.ARTICLEEnvironmental Research Letters2019

    NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission will collect waveform lidar data at a dense sample of ∼25 m footprints along ground tracks paralleling the orbit of the International Space Station (ISS). GEDI’s primary science deliverable will be a 1 km grid of estimated mean aboveground biomass density (Mg ha −1 ), covering the latitudes overflown by ISS (51.6 °S to 51.6 °N). One option for using the sample of waveforms contained wi…

  • Monitoring forest degradation from charcoal production with historical Landsat imagery. A case study in southern Mozambique

    Open AccessF Sedano, Sá Nogueira Lisboa et al.ARTICLEEnvironmental Research Letters2019

    We used historical Landsat imagery to monitor forest degradation from charcoal production in the main supplying region of the Mozambican capital, Maputo, during a ten-year period (2008–2018). We applied a change detection method that exploits temporal NDVI dynamics associated with charcoal production. This forest degradation temporal sequence exposes the magnitude and the spatial and temporal dynamics of charcoal production, which is the main for…
