From: Carbon emissions from the 2023 Canadian wildfires

a–c, May–September TROPOMI dry-air mole fractions of CO (XCO) averaged over 2019–2022 (a) and for 2023 (b) aggregated to a 2° × 2.5° grid. c, Canadian forest fire carbon emissions (from CO and CO2) for the 2023 May–September fire season, compared with fire emissions during 2010–2022 (distribution shown by box-and-whisker plots). Top-down emissions over 2010–2022 are estimated from MOPITT (2010–2021) and TROPOMI (2019–2022) CO retrievals. d, A comparison of May–September Canadian fire emissions with 2022 territorial fossil carbon emissions for the ten largest emitting countries, obtained from Global Carbon Budget 20222.
