Estimation of chlorophyll-a concentration from VIIRS ocean color data in Cambodia
MetadataShow full item record
A study on chlorophyll-a concentration on Cambodia water in the Gulf of Thailand was conducted using the Visible Infrared Imaging Radiometer Suite (VIIRS) to produce an estimation of global chlorophyll-a concentration. Field data was obtained from R/V Koyo-maru cruise No 49/2514 in 26 stations on November 2014 using calibration and validation. The study yielded results of a mean concentration of 1.467 mg/m3, minimum concentration of 0.503 mg/m3 and maximum concentration of 55.663 mg/m3. The relationship between field data and satellite data is Y = 1.721x + 0.291, where Y is field chlorophyll-a concentration and x is concentration from VIIRS product. The coefficient of determination (R2) is 0.245 which is lower than expected whereas RMSE from validation is 0.275 which is acceptable enough.
