A consistent climate data record of atmospheric methane from the GOSAT and GOSAT-2 missions

Robert James Parker, Michael P. Cartwright, Dan Orr, N.B. Lakshmi et autres

Abstract. Understanding the renewed and accelerating growth of atmospheric methane requires satellite records that are long enough to span decadal change and consistent enough that instrumental differences are not mistaken for atmospheric signals. We present version 2.0 of the University of Leicester …

The UOW FTIR trace gas analyser: comparison with LoFlo, AGAGE and tank measurements at Cape Grim and GASLAB

DAVID W. T. GRIFFITH, Nicholas Michael Deutscher, Paul B. Krummel, Paul J. Fraser et autres

Accurate baseline measurements of clean air composition are technically demanding, and benefit from advances in instrumentation which improve accuracy and lower the cost and effort of ownership. The University of Wollongong FTIR trace gas analyser for determination of atmospheric trace gas concentrations …

TCCON data from Wollongong (AU), Release GGG2020.1.R0

Nicholas Michael Deutscher, DAVID W. T. GRIFFITH, Clare Paton‐Walsh, Nicholas Brian Jones et autres

The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, …

Comparing v11.2 OCO‐2 and v11 OCO‐3 XCO2 Retrievals With Ground‐Based COCCON Measurements

Saswati Das, Mahesh Kumar Sha, Darko Dubravica, Thomas E. Taylor et autres

Abstract The Orbiting Carbon Observatory‐2 and ‐3 (collectively termed “OCO‐2/3,” hereafter) missions, together, provide precise and accurate global data records that contribute to a better understanding of the variability in atmospheric carbon dioxide (CO 2 ). The retrieval algorithm used to process …

TROPOMI/WFMD v2.0: Improved retrievals of XCH 4 and XCO with XGBoost-based quality filtering

Oliver Schneising, H. Bovensmann, Michael Buchwitz, Matthias H. Buschmann et autres

Abstract. The TROPOspheric Monitoring Instrument (TROPOMI) on board the Sentinel-5 Precursor satellite provides daily global observations of atmospheric methane (CH4) and carbon monoxide (CO) at relatively high spatial resolution. The dense spatial and temporal coverage is achieved by the instrument’s wide swath, …

The Post‐2020 Surge in Global Atmospheric Methane Observed in Ground‐Based Observations

Jennifer Wu, Sherry Luo, Zhao‐Cheng Zeng, Debra B. Wunch et autres

Abstract Methane (CH 4 ) is a potent greenhouse gas with high radiative forcing and a relatively short atmospheric lifetime of around a decade. We used a decade‐long data set (2011–2022) from the Fourier transform spectrometer at the California Laboratory for Atmospheric …

Annual growth rates of column-averaged CO$_2$ inferred from Total Carbon Column Observing Network (TCCON)

Nasrin Mostafavi Pak, Jonas Hachmeister, Markus Rettinger, Matthias H. Buschmann et autres

Monitoring annual atmospheric CO$_2$ growth rates is a key constraint on assessing the long-term effectiveness of emission reduction strategies. We analyzed annual growth rates of column-averaged dry-air mole fractions of CO$_2$ (XCO$_2$) using long-term data from 12 sites within the Total Carbon …
