Satellite \({R}_{rs}(\lambda )\) extracted from the bloom regions by a GOCI, b MODIS, and c MERIS images in Figs. 2 and 3. The K1-GOCI, K2-GOCI, K1-MODIS, K2-MODIS, K1-MERIS and K2-MERIS represent the averaged satellite \({R}_{\mathrm{rs}}(\lambda )\) of K. mikimotoi bloom regions from GOCI, MODIS and MERIS images in Fig. 2. The P1-GOCI, P2-GOCI, P1-MODIS, P2-MODIS, P1-MERIS and P2-MERIS represent the averaged satellite \({R}_{\mathrm{rs}}(\lambda )\) of P. donghaiense bloom regions from GOCI, MODIS and MERIS images in Fig. 3
