In order to remove the fluctuating atmospheric effects from the Case 2 water, an algorithm for retrieval of suspended sediment concentration from NOAA weather satellite imagery was developed under a new approach. 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 2 (R2, 720-1 100 nm). Proportional factor for this gradient transiting, mathematically represented as (td2/td1) (toz2/toz1), 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-R2 is selected to retrieve gradient a and then sea surface suspendend sediment concentration.
