These retrievals are generally performed over spectrally dark objects and therefore may struggle over bright surfaces. This study proposed an analytical TERRA-AQUA MODIS relationship in the reflective solar bands for aerosol retrieval. For the relationship development, the bidirectional reflectance distribution function (BRDF) effects were adjusted using reflectance ratios in the MODIS 2.13 \u03bcm band and the path radiance was approximated as an analytical function of aerosol optical thickness (AOT) and scattering phase function. Comparisons with MODIS observation data, MODIS AOT data, and sun photometer measurements demonstrate the validity of the proposed relationship for aerosol retrieval. The synergetic TERRA-AQUA MODIS retrievals are highly correlated with the ground measured AOT at TERRA MODIS overpass time (R2 = 0.617; RMSE = 0.043) and AQUA overpass time (R2 = 0.737; RMSE = 0.036). Compared to our retrievals, both the MODIS DT and DB retrievals are subject to severe underestimation. Sensitivity analyses reveal that the proposed method may perform better over non-vegetated than vegetated surfaces, which can offer a complement to MODIS operational algorithms. In an analytical form, the proposed method also has advantages in computational efficiency, and therefore can be employed for fine-scale (relative to operational 10 km MODIS product) MODIS aerosol retrieval. Overall, this study provides insight into aerosol retrievals and other applications regarding TERRA-AQUA MODIS data.<\/jats:p>","DOI":"10.3390\/rs8120996","type":"journal-article","created":{"date-parts":[[2016,12,5]],"date-time":"2016-12-05T10:27:09Z","timestamp":1480933629000},"page":"996","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Exploiting TERRA-AQUA MODIS Relationship in the Reflective Solar Bands for Aerosol Retrieval"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0099-1839","authenticated-orcid":false,"given":"Xingwang","family":"Fan","sequence":"first","affiliation":[{"name":"Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing 210008, China"},{"name":"Key Laboratory of Watershed Geographic Sciences, Chinese Academy of Sciences, Nanjing 210008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8780-927X","authenticated-orcid":false,"given":"Yuanbo","family":"Liu","sequence":"additional","affiliation":[{"name":"Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing 210008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1243","DOI":"10.1175\/1520-0442(2002)015<1243:TAVHRR>2.0.CO;2","article-title":"The advanced very high resolution radiometer (AVHRR) pathfinder atmosphere (PATMOS) climate dataset: Initial analyses and evaluations","volume":"15","author":"Stowe","year":"2002","journal-title":"J.
