Fig. 2. Statistical probability distribution of QA score of GOCI R_rs data processed by GDPS1.2, GDPS1.3, GDPS1.4.1 and GDPS2.0in Yellow Sea
(a): Histogram figure of QA score of R_rs date; (b): Graph figure of QA score of R_rs date

Fig. 3. Comparison analysis figures of R_rs data obtained from GOCI data processed by GDPS1.2, GDPS1.3, GDPS1.4.1 and GDPS2.0 with the in-situ measured R_rs data of four stations
The GOCI Rrs spectra obtained by GDPS1.3(green line) and GDPS1.4.1(blue line) are coincident (a), (b), (c), (d) correspond to the comparison results of the four stations from north to south in Figure 1 respectively

Fig. 4. (a) Comparison results between R_rs values processed by four GDPS versions of 469nm and field measured data; (b) Comparison results between R_rs values processed by four GDPS versions of 555 nm and field measured data; (c) Comparison results between R_rs-chla obtained from R_rs(469) and R_rs(555) processed by four GDPS versions and R_rs-chla data obtained from field measured data
