内容 研究概要:We propose a simple method of detecting dust-loaded airmass over the land area, which is based on the difference between Rayleigh-corrected reflectances at 412 nm and 443 nm bands of SeaWiFS data. The method, together with multi-band based cloud masking algorithm, is applied to '98 April SeaWiFS images of continental China, when a major dust event occurred. The resulted "dust aerosol index" imageries are compared with dust amount distribution predicted by a dust transport model, showing good general agreement. The correlation of the satellite-derived index and the predicted dust amount is discussed from the viewpoint of difference in the land cover.
