The thermophysical features of the mare units are studied in detail using the brightness temperature (TB) maps (TB, normalized TB, TB difference) derived from the CE-2 microwave radiometer data. The previously interpreted geological boundaries of the R\u00fcmker region are revisited in this study according to their TB behaviors: IR1, IR2, and IR3 R\u00fcmker plateau units are combined into one single unit (IR); and a hidden unit is found on the Mons R\u00fcmker; Mare basaltic units Im1 and Em1 are combined into Em1; and Em2 is more likely the extending of Im2. Each of the previous proposed landing sites and their scientific value are summarized and reevaluated. Based on this, four landing sites are recommended in order to maximize the scientific outcome of the CE-5 mission. We suggest that the Eratosthenian-aged Em4 and Em1 units as the top priority landing site for the CE-5 mission; the age-dating results will provide important clues concerning the thermal evolution of the Moon.<\/jats:p>","DOI":"10.3390\/rs12193272","type":"journal-article","created":{"date-parts":[[2020,10,9]],"date-time":"2020-10-09T10:19:23Z","timestamp":1602238763000},"page":"3272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Thermophysical Features of the R\u00fcmker Region in Northern Oceanus Procellarum: Insights from CE-2 CELMS Data"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4598-087X","authenticated-orcid":false,"given":"Zhiguo","family":"Meng","sequence":"first","affiliation":[{"name":"College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China"},{"name":"State Key Laboratory of Resources and Environmental Information System, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Institute of National Development and Security Studies, Jilin University, Changchun 130026, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1017-9772","authenticated-orcid":false,"given":"Jietao","family":"Lei","sequence":"additional","affiliation":[{"name":"College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7119-5501","authenticated-orcid":false,"given":"Yuqi","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, China University of Geosciences, Wuhan 430074, China"},{"name":"Departmental of Earth, Environmental, and Planetary Sciences, Brown University, Providence, RI 02912, USA"}]},{"given":"Long","family":"Xiao","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, China University of Geosciences, Wuhan 430074, China"}]},{"given":"James W.","family":"Head","sequence":"additional","affiliation":[{"name":"Departmental of Earth, Environmental, and Planetary Sciences, Brown University, Providence, RI 02912, USA"}]},{"given":"Shengbo","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1580-4979","authenticated-orcid":false,"given":"Weiming","family":"Cheng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Resources and Environmental Information System, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6163-2912","authenticated-orcid":false,"given":"Jiancheng","family":"Shi","sequence":"additional","affiliation":[{"name":"National Space Science Center, Chinese Academy of Sciences, Beijing 100012, China"}]},{"given":"Jinsong","family":"Ping","sequence":"additional","affiliation":[{"name":"Key Laboratory of Lunar and Deep Space Exploration, National Astronomical Observatory, Chinese Academy of Sciences, Beijing 100012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9728-4702","authenticated-orcid":false,"given":"Zhizhong","family":"Kang","sequence":"additional","affiliation":[{"name":"School of Land Science and Technology, China University of Geosciences, Beijing 100083, China"},{"name":"Subcenter of International Cooperation and Research on Lunar and Planetary Exploration, Center of Space Exploration, Ministry of Education of the People\u2019s Republic of China, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1419","DOI":"10.1002\/2016JE005247","article-title":"The Mons R\u00fcmker volcanic complex of the Moon: A candidate landing site for the Chang\u2019E-5 mission","volume":"122","author":"Zhao","year":"2017","journal-title":"J.
