This paper presents the calibration and validation results of the OCTS's ocean color information, e.g., the chlorophyll-a (CHL-a), and the normalized water leaving radiance (nLw). First, OCTS was calibrated for interdetector sensitivity, dark current variability, and absolute gain using internal and external calibration sources. Second, OCTS ocean color information was validated using in-situ measurements for CHL-a and nLw. The atmospheric correction algorithm was tuned using 17 in-situ CHL-a and 11 in-situ nLw measurements, which were observed simultaneously with OCTS under cloud-free conditions. It was then confirmed that OCTS CHL-a has an accuracy of 68%. Furthermore, it was also confirmed that geometric accuracy is 1.3 km and stripes are reduced significantly.
