| description | <p>The Sentinel-5 Precursor (S5P) mission with the TROPOspheric Monitoring Instrument (TROPOMI) on board has been measuring solar radiation backscattered by the Earth's atmosphere and surface since its launch on 13 October 2017. In this paper, we present for the first time the S5P operational methane (<span class="inline-formula">CH<sub>4</sub></span>) and carbon monoxide (CO) products' validation results covering a period of about 3 years using global Total Carbon Column Observing Network (TCCON) and Infrared Working Group of the Network for the Detection of Atmospheric Composition Change (NDACC-IRWG) network data, accounting for a priori alignment and smoothing uncertainties in the validation, and testing the sensitivity of validation results towards the application of advanced co-location criteria. We found that the S5P standard and bias-corrected <span class="inline-formula">CH<sub>4</sub></span> data over land surface for the recommended quality filtering fulfil the mission requirements. The systematic difference of the bias-corrected total column-averaged dry air mole fraction of methane (<span class="inline-formula">XCH<sub>4</sub></span>) data with respect to TCCON data is <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M5" display="inline" overflow="scroll" dspmath="mathml"><mrow><mo>-</mo><mn mathvariant="normal">0.26</mn><mo>±</mo><mn mathvariant="normal">0.56</mn></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="64pt" height="10pt" class="svg-formula" dspmath="mathimg" md5hash="cf12f1ebda09b23099609c4f56d721cb"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="amt-14-6249-2021-ie00001.svg" width="64pt" height="10pt" src="amt-14-6249-2021-ie00001.png"/></svg:svg></span></span> % in comparison to <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M6" display="inline" overflow="scroll" dspmath="mathml"><mrow><mo>-</mo><mn mathvariant="normal">0.68</mn><mo>±</mo><mn mathvariant="normal">0.74</mn></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="64pt" height="10pt" class="svg-formula" dspmath="mathimg" md5hash="9ae74d02ec25319b16974d15a6879a7e"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="amt-14-6249-2021-ie00002.svg" width="64pt" height="10pt" src="amt-14-6249-2021-ie00002.png"/></svg:svg></span></span> % for the standard <span class="inline-formula">XCH<sub>4</sub></span> data, with a correlation of 0.6 for most stations.
