This is the first of periodic updates to the tables and figures compiled following similar methods with updated measurements from the community of scientists who monitor the global distributions of these compounds in the troposphere.\r\n\r\nThe datafile, Tracer_atmospheric_histories_revised_2023_Table1.csv, and Table 1 list the annual mean tropospheric concentrations of CFC-11, CFC-12, CFC-113, CCl4, SF6, and N2O in the northern and southern hemispheres (NH, SH) from 1765.5 to 2022.5. The reported values are the annual (Jan-Dec) mean mole fraction of these gases in dry air. Concentrations are in parts per trillion (ppt) for CFC-11, CFC-12, CFC-113, CCl4, and SF6; and in parts per billion (ppb) for N2O.\r\n \r\n \r\n This dataset is available to the public for a wide variety of uses including scientific research and analysis.\r\n \r\n \r\n Funding Information: NOAA\r\n \r\n \r\n completed\r\n \r\n \r\n historicalArchive\r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n HTTPS\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n asNeeded\r\n \r\n \r\n NCEI Accession 0164584 was revised and a new version of the archival package was published.

(2000) results found at bluemoon.ucsd.edu/pub/cfchist. The concentrations for these trace gases from 2009.5 to 2022.5 are derived from the NOAA gas sampling program formerly known as CMDL, now known as GML (Global Monitoring Laboratory). These NOAA data are tabulated through Feb. 2023 (as of June 2023) and can be located in the subdirectories of https://gml.noaa.gov/aftp/data/hats/. Following the procedure of Bullister (2017), the changes in the annual average (Jan-Dec) concentrations of the trace gases in ppt were added to the Walker et al. data. The sum of the changes in concentrations between 2008.5 and 2019.5 in the GML data set are slightly different than the differences in the global mean concentrations reported by the AGAGE measurement program (https://agage2.eas.gatech.edu/data_archive/global_mean/) which may indicate a small systematic offset. These differences are consistent with those reported by Rigby et al. (2013) for the earlier part of this time period.\r\n \r\n \r\n \r\n \r\n \r\n \r\n Parameter or Variable: SF6;\r\nAbbreviation: SF6;\r\nDetailed sampling and analyzing information: Bullister (2017) normalized the cumulative production and release estimates of this compound to the measured atmospheric concentrations of this tracer in the Northern and Southern Hemispheres in June 1995 by the NOAA gas sampling program \u2013 currently found at https://gml.noaa.gov/aftp/hats/sf6/combined/HATS_global_SF6.txt. In Table 1, the SF6 values from 1996.5 to 2022.5 are the mean annual NH and SH values reported by GML. Note that the GML concentrations are now reported on the NOAA 2014 scale, instead of the CMDL2006 scale as in Bullister (2017). Although the conversion between the two NOAA scales requires solving a quadratic equation (see https://gml.noaa.gov/ccl/sf6_scale.html) to revert to the CMDL 2006 scale, Krummell et al. (2017) reported that NOAA 2014/ SIO 2005 = 1.002 (\u00b1 0.002). The SF6 data in Table 1 are reported on the SIO2005 scale using this conversion factor. The AGAGE program reports SF6 concentrations beginning in 2004. A comparison of the increase in reported atmospheric concentrations between 2004.5 and 2020.5 differ by less than 0.20 ppt between AGAGE (increase of 4.88 ppt in 16 y) and GML (increase of 4.76 ppt (NH) and 4.68 ppt (SH) in 16 y).\r\n \r\n \r\n \r\n \r\n \r\n \r\n Parameter or Variable: N2O;\r\nAbbreviation: N2O;\r\nDetailed sampling and analyzing information: Bullister (2017) fitted a linear non-polynomial function to the combined ice core measurements (1502-1996) and CMDL atmospheric measurements (1978-2015) of N2O concentrations. In the plots of the residuals of the data to this fit (Figs. 10 and 11, Bullister 2017), there appears to be a slight positive bias in the most recent atmospheric measurements. In this update, the N2O concentrations reported in Table 1 after 2010.5 are the annual averages from the GML data (https://gml.noaa.gov/aftp/data/hats/n2o/combined/), although the data prior to 2010.5 are calculated from the fitted data through 2015.5. The difference in N2O values in Table 1 from those in Table 1 of Bullister (2017) for 2010.5 to 2015.5 are (in ppb).\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n asNeeded\r\n \r\n \r\n Metadata are developed, maintained and distributed by NCEI.
