Dust deposited on the vegetation canopy may change its spectra. However, a relationship between canopy spectra and dust amount has not been quantitatively studied, and a pixel-scale condition for remote sensing application has not been considered yet. In this study, the dust dispersion characteristics in an iron mining area were investigated using the American Meteorological Society (AMS) and the U.S. Environmental Protection Agency (EPA) regulatory model (AERMOD). Further, based on the three-dimensional discrete anisotropic radiative transfer (DART) model, the spectral characteristics of vegetation canopy under the dusty condition were simulated, and the influence of dustfall on vegetation canopy spectra was studied. Finally, the dust effect on vegetation spectra at the canopy scale was extended to a pixel scale, and the response of dust effect on vegetation spectra at the pixel scale was determined under different fractional vegetation covers (FVCs). The experimental results show that the dust pollution along a haul road was more severe and extensive than that in a stope. Taking dust dispersion along the road as an example, the variation of vegetation canopy spectra increased with the height of dust deposited on the vegetation canopy. At the pixel scale, a lower vegetation FVC would weaken the influence of dust on the spectra. The results derived from simulation spectral data were tested using satellite remote sensing images. The tested result indicates that the influence of dust retention on the pixel spectra with different FVCs was consistent with that created with the simulated data. The finding could be beneficial for those making decisions on monitoring vegetation under dusty conditions and reducing dust pollution in mining areas using remote sensing technology.<\/jats:p>","DOI":"10.3390\/rs12223759","type":"journal-article","created":{"date-parts":[[2020,11,16]],"date-time":"2020-11-16T21:48:52Z","timestamp":1605563332000},"page":"3759","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Dust Dispersion and Its Effect on Vegetation Spectra at Canopy and Pixel Scales in an Open-Pit Mining Area"],"prefix":"10.3390","volume":"12","author":[{"given":"Baodong","family":"Ma","sequence":"first","affiliation":[{"name":"Key Laboratory of Ministry of Education on Safe Mining of Deep Metal Mines, Northeastern University, Shenyang 110819, China"},{"name":"Institute for Geoinformatics &amp; Digital Mine Research, Northeastern University, Shenyang 110819, China"}]},{"given":"Xuexin","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education on Safe Mining of Deep Metal Mines, Northeastern University, Shenyang 110819, China"},{"name":"Institute for Geoinformatics &amp; Digital Mine Research, Northeastern University, Shenyang 110819, China"}]},{"given":"Ziwei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education on Safe Mining of Deep Metal Mines, Northeastern University, Shenyang 110819, China"},{"name":"Institute for Geoinformatics &amp; Digital Mine Research, Northeastern University, Shenyang 110819, China"}]},{"given":"Ruiliang","family":"Pu","sequence":"additional","affiliation":[{"name":"School of Geosciences, University of South Florida, Tampa, FL 33620, USA"}]},{"given":"Aiman","family":"Liang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education on Safe Mining of Deep Metal Mines, Northeastern University, Shenyang 110819, China"},{"name":"Institute for Geoinformatics &amp; Digital Mine Research, Northeastern University, Shenyang 110819, China"}]},{"given":"Defu","family":"Che","sequence":"additional","affiliation":[{"name":"Key Laboratory of Ministry of Education on Safe Mining of Deep Metal Mines, Northeastern University, Shenyang 110819, China"},{"name":"Institute for Geoinformatics &amp; Digital Mine Research, Northeastern University, Shenyang 110819, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1479","DOI":"10.1029\/2000GL012647","article-title":"Absorption of sunlight by dust as inferred from satellite and ground-based remote sensing","volume":"28","author":"Kaufman","year":"2001","journal-title":"Geophys.
