STATISTICAL INVERSION MODEL FOR CHLOROPHYLL A CONCENTRATION IN THE BOHAI

摘要

Bio-optical observations of about 50 stations were carried out in June, 2005 in Bohai, the major area of which belongs to Optical Case II water. The experiment acquired apparent optical properties, inherent optical properties, biological, chemical and water quality data, in accordance with NASA Ocean Optics Protocols. Using these data, a statistical inversion model of chlorophyll a concentration (chl-a) of Bohai was developed based on MERIS bands configuration. The inversion model has the performance of 29.83% average relative error (ARE) and 16.45% root mean square error (RMSE) between the measured and inversed data.
