The observation bias and observation error characteristics of MWHS-2 are evaluated by using ERA-5 as the background field. The results show that the biases range from \u22124 to 2 K, and the observation errors are within 1.5 K except for the window channels. A further analysis of the dependence on the scanning angles indicates that observation errors for the window channels and the 118-GHz channels increase with decreasing scanning angles. Observation errors of the window channels and water vapor channels are also latitudinally dependent, and the maximum errors in the high latitudes reach 2.0 K, while those in the tropical regions are approximately 0.8 K. In addition, the observed brightness temperature of FY-3E MWHS-2 is accompanied by striping noises along the track and high-frequency oscillation noises along the scanlines. The noise mitigation results show that both noises are approximately 0.2 K.<\/jats:p>","DOI":"10.3390\/rs14194835","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T22:53:19Z","timestamp":1664405599000},"page":"4835","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Performance Evaluation and Noise Mitigation of the FY-3E Microwave Humidity Sounder"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3608-5603","authenticated-orcid":false,"given":"Jiali","family":"Mao","sequence":"first","affiliation":[{"name":"Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters, Nanjing University of Information Science and Technology, Nanjing 211544, China"},{"name":"Joint Center for Data Assimilation for Research and Application, Nanjing University of Information Science and Technology, Nanjing 211544, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1172-8040","authenticated-orcid":false,"given":"Zhengkun","family":"Qin","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters, Nanjing University of Information Science and Technology, Nanjing 211544, China"},{"name":"Joint Center for Data Assimilation for Research and Application, Nanjing University of Information Science and Technology, Nanjing 211544, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"CMA Earth System Modeling and Prediction Centre, Beijing 100081, China"},{"name":"State Key Laboratory of Severe Weather, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2049-7678","authenticated-orcid":false,"given":"Yang","family":"Han","sequence":"additional","affiliation":[{"name":"CMA Earth System Modeling and Prediction Centre, Beijing 100081, China"},{"name":"State Key Laboratory of Severe Weather, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Huang","sequence":"additional","affiliation":[{"name":"CMA Earth System Modeling and Prediction Centre, Beijing 100081, China"},{"name":"State Key Laboratory of Severe Weather, Beijing 100081, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s00376-021-1304-7","article-title":"FY-3E: The first operational meteorological satellite mission in an early-morning orbit","volume":"39","author":"Zhang","year":"2021","journal-title":"Adv.
