  • Global Carbon Budget 2023

    Open AccessPierre Friedlingstein, Mike O’Sullivan et al.ARTICLEEarth System Science Data2023

    Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate is critical to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe and synthesize data sets and methodology to quantify the five major components of the global carbon budget and their uncertai…

  • A declining trend of methane emissions in the Los Angeles basin from 2015 to 2020

    Open AccessVineet Yadav, K R Verhulst et al.ARTICLEEnvironmental Research Letters2023

    The Los Angeles (LA) basin was responsible for approximately 20% of California’s methane emissions in 2016. Hence, curtailment of these emissions is required to meet California’s greenhouse gas emissions reduction targets. However, effective mitigation remains challenging in the presence of diverse methane sources like oil and gas production fields, refineries, landfills, wastewater treatment facilities, and natural gas infrastructure. In this st…

  • Atmospheric verification of emissions reductions on paths to deep decarbonization

    Open AccessAhmed Abdulla, Fabian JE Telschow et al.ARTICLEEnvironmental Research Letters2023

    A central challenge for sustaining international cooperation to cut global greenhouse gas emissions is confidence that national policy efforts are leading to a meaningful impact on the climate. Here, we apply a detection protocol to determine when the measurable signal of atmospheric CO 2 can be distinguished from the noise of the carbon cycle and uncertainties in emission trends. We test that protocol with a database of 226 emission mitigation s…

  • Assessing fossil fuel CO 2 emissions in California using atmospheric observations and models

    Open AccessHeather Graven, M L Fischer et al.ARTICLEEnvironmental Research Letters2018

    Analysis systems incorporating atmospheric observations could provide a powerful tool for validating fossil fuel CO 2 (ffCO 2 ) emissions reported for individual regions, provided that fossil fuel sources can be separated from other CO 2 sources or sinks and atmospheric transport can be accurately accounted for. We quantified ffCO 2 by measuring radiocarbon ( 14 C) in CO 2 , an accurate fossil-carbon tracer, at nine observation sites in Californi…

  • Global Carbon Budget 2016

    Open AccessCorinne Le Quéré, Robbie M Andrew et al.ARTICLEEarth System Science Data2016

    Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global carbon budget” – is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe data sets and methodology to quantify all major components of the global carbon budget, including their uncertainti…

  • Methods for High-Precision 14 C AMS Measurement of Atmospheric CO 2 at LLNL

    Open AccessHeather D Graven, Thomas P Guilderson et al.ARTICLERadiocarbon2007Cited by: 9References: 17

    Development of radiocarbon analysis with precision better than 2% has the potential to expand the utility of 14 CO 2 measurements for carbon cycle investigations as atmospheric gradients currently approach the typical measurement precision of 2–5%. The accelerator mass spectrometer at Lawrence Livermore National Laboratory (LLNL) produces high and stable beam currents that enable efficient acquisition times for large numbers of 14 C counts. One m…
