| Abstract: | <p><strong>Abstract.</strong> A severe reduction of greenhouse gas emissions is necessary to reach the objectives of the Paris Agreement. The implementation and continuous evaluation of mitigation measures requires regular independent information on emissions of the two main anthropogenic greenhouse gases, carbon dioxide (<span class="inline-formula">CO<sub>2</sub></span>) and methane (<span class="inline-formula">CH<sub>4</sub></span>). Our aim is to employ an observation-based method to determine regional-scale greenhouse gas emission estimates with high accuracy. We use aircraft- and ground-based in situ observations of <span class="inline-formula">CH<sub>4</sub></span>, <span class="inline-formula">CO<sub>2</sub></span>, carbon monoxide (CO), and wind speed from two research flights over the Upper Silesian Coal Basin (USCB), Poland, in summer 2018. The flights were performed as a part of the Carbon Dioxide and Methane (CoMet) mission above this European <span class="inline-formula">CH<sub>4</sub></span> emission hot-spot region. A kriging algorithm interpolates the observed concentrations between the downwind transects of the trace gas plume, and then the mass flux through this plane is calculated. Finally, statistic and systematic uncertainties are calculated from measurement uncertainties and through several sensitivity tests, respectively.</p> <p>For the two selected flights, the in-situ-derived annual <span class="inline-formula">CH<sub>4</sub></span> emission estimates are <span class="inline-formula">13.8±4.3</span> and <span class="inline-formula">15.1±4.0</span> kg s<span class="inline-formula"><sup>−1</sup></span>, which are well within the range of emission inventories. The regional emission estimates of <span class="inline-formula">CO<sub>2</sub></span>, which were determined to be <span class="inline-formula">1.21±0.75</span> and <span class="inline-formula">1.12±0.38</span> t s<span class="inline-formula"><sup>−1</sup></span>, are in the lower range of emission inventories. CO mass balance emissions of <span class="inline-formula">10.1±3.6</span> and <span class="inline-formula">10.7±4.4</span> kg s<span class="inline-formula"><sup>−1</sup></span> for the USCB are slightly higher than the emission inventory values. The <span class="inline-formula">CH<sub>4</sub></span> emission estimate has a relative error of 26 %-31 %, the <span class="inline-formula">CO<sub>2</sub></span> estimate of 37 %-62 %, and the CO estimate of 36 %-41 %. These errors mainly result from the uncertainty of atmospheric background mole fractions and the changing planetary boundary layer height during the morning flight. In the case of <span class="inline-formula">CO<sub>2</sub></span>, biospheric fluxes also add to the uncertainty and hamper the assessment of emission inventories. These emission estimates characterize the USCB and help to verify emission inventories and develop climate mitigation strategies.</p> |
