In remote chlorophyll-a (Chla) retrieval in Case-II waters, the uncertainties from Chla specific absorption coefficient a*ph has a significant effect on the retrieving accuracy. In this paper, we presented newly improved three-band model and four-band model by a case study in Shitoukoumen Reservoir. The proposed three-band model can be expressed as [Rrs-1 (λ1)-Rrs-1 (λ2)]×Rrs(λ3)×a*ph-1 (λ1), while the improved four-band model is [Rrs-1 (λ1)-Rrs-1 (λ2)]×[Rrs-1(λ4)×Rrs-1(λ3)]-1×a*ph-1(λ1). Results showed that the latter one was slightly superior to the former one. Comparison with original models without correction of a*ph, the improved models achieved higher precision and stability. The findings underlined the rationale behind the proposed models and demonstrated a potentially use for assessing Chla in Case-II waters. |
