 <p>To assess if the uncertainty, spatial/temporal resolution and coverage of satellite-based observations are sufficient to investigate year-to-year anomalies in CH4 emissions of tropical wetlands, we inspected the documentation of the CDS dataset “Methane data from 2002 to present derived from satellite observations” (<a class="reference external" href="https://cds-beta.climate.copernicus.eu/datasets/satellite-methane?tab=overview">[7]</a>, <a class="reference external" href="http://wdc.dlr.de/C3S_312b_Lot2/Documentation/GHG/C3S2_312a_Lot2_PUGS_GHG_main_latest.pdf">[6]</a>, <a class="reference external" href="http://wdc.dlr.de/C3S_312b_Lot2/Documentation/GHG/C3S2_312a_Lot2_PQAR_GHG_main_latest.pdf">[8]</a>) as well as a case study available from scientific literature (<a class="reference external" href="https://doi.org/10.1016/j.rse.2018.02.011">[9]</a>). Please note that to analyse annual anomalies in wetland methane emissions, <a class="reference external" href="https://doi.org/10.1016/j.rse.2018.02.011">[9]</a> used an earlier version (v7) of Level 2 data from the CH4_GOS_OCPR data product.</p>

 <p>The data product used by <a class="reference external" href="https://doi.org/10.1016/j.rse.2018.02.011">[9]</a> was characterised by a random error of 13 ppb and a relative spatial bias of 2 ppb with respect to TCCON co-located observations (<a class="reference external" href="https://doi.org/10.5194/acp-21-4339-2021">[10]</a>). According with <a class="reference external" href="http://wdc.dlr.de/C3S_312b_Lot2/Documentation/GHG/C3S2_312a_Lot2_PQAR_GHG_main_latest.pdf">[8]</a>, the <strong>Level 2 XCH4 products</strong> of the dataset “Methane data from 2002 to present derived from satellite observations” have <strong>uncertainties comparable to those of the dataset used by <a class="reference external" href="https://doi.org/10.1016/j.rse.2018.02.011">[9]</a></strong>: individual measurement accuracies are typically less than 20 ppb (13 ppb for the latest version of CH4_GOS_OCPR), while the relative spatial bias is less than 6.2 ppb (4 ppb for CH4_GOS_OCPR). Moreover, <strong>except for the SCIAMACHY XCH4 products</strong>, the single measurements random errors are close to the “breakthrough” requirement (&lt; 17 ppb) defined by the  Climate Research Group (CRG) of the ESA GHG-CCI project for the usability of satellite measurements to derive information on regional scale sources and sink of methane <a class="reference external" href="https://www.iup.uni-bremen.de/carbon_ghg/docs/GHGCCIplus/URD/URDv3.0_GHG-CCIp_Final.pdf">[11]</a>.</p>
