  • Enhanced observation of forest albedo reveals significant offsets to reported carbon benefits

    Open AccessSEAN P HEALEY, Zhiqiang Yang et al.ARTICLEEnvironmental Research Letters2025

    Rapidly maturing frameworks for investing in and committing to mitigation of climate change through forest management have focused almost exclusively on the benefits of carbon sequestration, without accounting for collateral changes in geophysical factors such as surface albedo. Newly available 30 m albedo retrievals derived from imagery acquired by the Landsat 8 satellite, analyzed at 273 652 field plots monitored by the United States Forest Ser…

  • Vicarious calibration of Gedi biomass with Landsat age data for understanding secondary forest carbon dynamics

    Open AccessNidhi Jha, SEAN P HEALEY et al.ARTICLEEnvironmental Research Letters2024

    The recovery of biomass in secondary forests plays a vital role in global carbon sequestration processes and carbon emission mitigation. However, accurately quantifying the accumulation rate of aboveground biomass density in these forests is challenging owing to limited longitudinal field data. An alternative monitoring strategy is characterizing the mean biomass at a single point in time across stands with a range of known ages. This chronoseque…

  • 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…

  • A global time series dataset to facilitate forest greenhouse gas reporting

    Open AccessNoel Gorelick, Zhiqiang Yang et al.ARTICLEEnvironmental Research Letters2023

    We have developed a version of the Continuous Change Detection and Classification algorithm within the Google Earth Engine environment. It has been used with 20 years of Landsat data (1999–2019) to produce a new, publicly available global dataset of pre-computed time series break points and harmonic coefficients. We present results from regional use cases demonstrating classification and change detection with this new dataset and compare them to …

  • 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…

  • The Nasa Carbon Monitoring System Phase 2 synthesis

    Open AccessG C Hurtt, A E Andrews et al.ARTICLEEnvironmental Research Letters2022

    Underlying policy efforts to address global climate change is the scientific need to develop the methods to accurately measure and model carbon stocks and fluxes across the wide range of spatial and temporal scales in the Earth system. Initiated in 2010, the NASA Carbon Monitoring System is one of the most ambitious relevant science initiatives to date, exploiting the satellite remote sensing resources, computational capabilities, scientific know…

  • Detecting vulnerability of humid tropical forests to multiple stressors

    Open AccessSassan Saatchi, Marcos Longo et al.ARTICLEOne Earth2021

  • Long-term forest health implications of roadlessness

    Open AccessSEAN P HEALEYARTICLEEnvironmental Research Letters2020

    The 2001 Forest Service Roadless Rule prohibits roadbuilding in forests across an area equivalent to the combined states of New York and Maine (236 000 km 2 ). There have been recent assertions that roads are needed to prevent fire and to keep forests healthy. Despite twenty years of ongoing forest health monitoring and the unique scope and ecological significance of this network of roadless areas, there has to date been no integrated assessment …

  • 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…
