temperature, resulting in a changing cryosphere, increasing human activity, and potentially increasing high-latitude methane emissions. Satellite observations from Sentinel-5P TROPOMI provide an unprecedented coverage of a column-averaged dry-air mole fraction of methane (XCH4) in the Arctic, compared to previous missions or in situ measurements. The purpose of this study is to support and enhance the data used for high-latitude research through presenting a systematic evaluation of TROPOMI methane products derived from two different processing algorithms: the operational product (OPER) and the scientific product (WFMD), including the comparison of recent version changes of the products (OPER, OPER rpro, WFMD v1.2, and WFMD v1.8). One finding is that OPER rpro yields lower XCH4 than WFMD v1.8, the difference increasing towards the highest latitudes. TROPOMI product differences were evaluated with respect to ground-based high-latitude references, including four Fourier Transform Spectrometer in the Total Carbon Column Observing Network (TCCON) and five EM27\/SUN instruments in the Collaborative Carbon Column Observing Network (COCCON). The mean TROPOMI\u2013TCCON GGG2020 daily median XCH4 difference was site-dependent and varied for OPER rpro from \u22120.47 ppb to 22.4 ppb, and for WFMD v1.8 from 1.2 ppb to 19.4 ppb with standard deviations between 13.0 and 20.4 ppb and 12.5\u201315.0 ppb, respectively. The TROPOMI\u2013COCCON daily median XCH4 difference varied from \u221226.5 ppb to 5.6 ppb for OPER rpro, with a standard deviation of 14.0\u201328.7 ppb, and from \u22125.0 ppb to 17.2 ppb for WFMD v1.8, with a standard deviation of 11.5\u201313.0 ppb. Although the accuracy and precision of both TROPOMI products are, on average, good compared to the TCCON and COCCON, a persistent seasonal bias in TROPOMI XCH4 (high values in spring; low values in autumn) is found for OPER rpro and is reflected in the higher standard deviation values. A systematic decrease of about 7 ppb was found between TCCON GGG2014 and GGG2020 product update highlighting the importance of also ensuring the reliability of ground-based retrievals. Comparisons to atmospheric profile measurements with AirCore carried out in Sodankyl\u00e4, Northern Finland, resulted in XCH4 differences comparable to or smaller than those from ground-based remote sensing.<\/jats:p>","DOI":"10.3390\/rs16162979","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T09:20:51Z","timestamp":1723627251000},"page":"2979","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Evaluation
