The aerosol optical thickness (AOT), which infers the aerosol burden, is used to measure the satellite monitoring capabilities. AOT products retrieved from POLDER on low aerosol loading days, and products from a radiometric instrument (MODIS) on high and low aerosol loading days, are presented for comparison. Our study reveals that for high aerosol days, the monitoring capability of the polarized instrument is lower than that of the traditional instrument. The accuracy of matched POLDER fine-AOTs is lower than that of MODIS-matched AOTs. On low aerosol loading days, the performance of the polarized instrument is good when monitoring the aerosol optical thickness. Further analysis reveals that for the high aerosol loading days, the mean relative errors of matched POLDER fine AOTs and MODIS AOTs with respect to AERONET measurements are 44% and 16%, respectively. For the low aerosol loading days, the mean relative errors of POLDER and MODIS measurements with respect to AERONET measurements are 41% and 40%, respectively. During high aerosol days, POLDER-retrieved fine-AOTs reveal a poor accuracy with only 14% of matches falling within the error range, which is nearly one fourth of the MODIS regression results (51.59%). For the low aerosol loading days, the POLDER regression results are good. Approximately 62% of the POLDER measurements fall within the expected error  range \u00b1(0.05 + 15%) compared with the AERONET observed values.<\/jats:p>","DOI":"10.3390\/rs71013711","type":"journal-article","created":{"date-parts":[[2015,10,20]],"date-time":"2015-10-20T16:21:51Z","timestamp":1445358111000},"page":"13711-13728","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Evaluation of Polarized Remote Sensing of Aerosol Optical Thickness Retrieval over China"],"prefix":"10.3390","volume":"7","author":[{"given":"Hao","family":"Chen","sequence":"first","affiliation":[{"name":"State Key Laboratory of Remote Sensing Science, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing, 100101 China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7889-9579","authenticated-orcid":false,"given":"Tianhai","family":"Cheng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Remote Sensing Science, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing, 100101 China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6370-799X","authenticated-orcid":false,"given":"Xingfa","family":"Gu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Remote Sensing Science, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing, 100101 China"}]},{"given":"Zhengqiang","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Remote Sensing Science, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing, 100101 China"}]},{"given":"Yu","family":"Wu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Remote Sensing Science, Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences, Beijing, 100101 China"}]}],"member":"1968","published-online":{"date-parts":[[2015,10,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2119","DOI":"10.1126\/science.1064034","article-title":"Aerosols, climate, and the hydrological cycle","volume":"294","author":"Ramanathan","year":"2001","journal-title":"Science"},{"key":"ref_2","unstructured":"Seinfeld, J.H., and Pandis, S.N.
