This model is based on the linear response from water-leaving to satellite-detected reflectance spectra, simply reflected by the gradient for correlation curve between reflectance of the advanced very high resolution radiometer (AVHRR) channels 1 (R1, 580–680 nm) and 2R 2, 720–1100 nm). Proportional factor for this gradient transiting, mathematically represented as (td2÷td1) (t0z2÷toz1g), depends on a ratio of atmospheric transmittance for such two channels, including ozone and diffuse transmittance. As a simple but efficient algorithm of gradient, the algorithm of αR1 R 2 is selected to retrieve gradient α and then sea surface suspendend sediment concentration. %K marine remote sensing %K suspended sediment %K atmospheric effect removal %K gradient transit %K AVHRR
