• Methane emissions in the United States, Canada, and Mexico: evaluation of national methane emission inventories and 2010-2017 sectoral trends by inverse analysis of in situ (GLOBALVIEWplus CH.sub.4 ObsPack) and satellite (GOSAT) atmospheric observations.

  Authors:Xiao Lu, Daniel J. Jacob, Haolin Wang, Joannes D. Maasakkers, Yuzhong Zhang, Tia R. Scarpelli, et al.From:Atmospheric Chemistry and Physics (Vol. 22, Issue 1) Peer-Reviewed

  Jan. 12, 2022499 words Article We quantify methane emissions and their 2010-2017 trends by sector in the contiguous United States (CONUS), Canada, and Mexico by inverse analysis of in situ (GLOBALVIEWplus CH.sub.4 ObsPack) and satellite (GOSAT)...

• Global distribution of methane emissions: a comparative inverse analysis of observations from the TROPOMI and GOSAT satellite instruments.

  Authors:Zhen Qu, Daniel J. Jacob, Lu Shen, Xiao Lu, Yuzhong Zhang, Tia R. Scarpelli, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 18) Peer-Reviewed

  Sept. 24, 2021422 words Article We evaluate the global atmospheric methane column retrievals from the new TROPOMI satellite instrument and apply them to a global inversion of methane sources for 2019 at 2.sup." x 2.5.sup." horizontal resolution. We...

• Reduced-cost construction of Jacobian matrices for high-resolution inversions of satellite observations of atmospheric composition.

  Authors:Hannah Nesser, Daniel J. Jacob, Joannes D. Maasakkers, Tia R. Scarpelli, Melissa P. Sulprizio, Yuzhong Zhang, et al.From:Atmospheric Measurement Techniques (Vol. 14, Issue 8) Peer-Reviewed

  Aug. 12, 2021385 words Brief article Global high-resolution observations of atmospheric composition from satellites can greatly improve our understanding of surface emissions through inverse analyses. Variational inverse methods can optimize surface...

• Global methane budget and trend, 2010-2017: complementarity of inverse analyses using in situ (GLOBALVIEWplus CH.sub.4 ObsPack) and satellite (GOSAT) observations.

  Authors:Xiao Lu, Daniel J. Jacob, Yuzhong Zhang, Joannes D. Maasakkers, Melissa P. Sulprizio, Lu Shen, et al.From:Atmospheric Chemistry and Physics (Vol. 21, Issue 6) Peer-Reviewed

  Mar. 25, 2021405 words Brief article We use satellite (GOSAT) and in situ (GLOBALVIEWplus CH4 ObsPack) observations of atmospheric methane in a joint global inversion of methane sources, sinks, and trends for the 2010-2017 period. The inversion is done by...

• Global distribution of methane emissions, emission trends, and OH concentrations and trends inferred from an inversion of GOSAT satellite data for 2010-2015

  Authors:Joannes D. Maasakkers, Daniel J. Jacob, Melissa P. Sulprizio, Tia R. Scarpelli, Hannah Nesser, Jian-Xiong Sheng, et al.From:Atmospheric Chemistry and Physics (Vol. 19, Issue 11) Peer-Reviewed
