Abstract
Advanced Earth Observation Satellite-II (ADEOS-II) was launched on December 14, 2002, and it operated from April to October 2003. One of the core sensors of ADEOS-II is Global Imager (GLI) which measured ocean color. Ocean color measurement is important because phytoplankton biomass (chlorophyll-a) is one of the most important parameter for estimating ocean primary production and associated carbon flux in the ocean. Cooperation study between JAXA and Nagasaki University was started from 2000. The study covered 1) collection of in situ data for calibration and validation of ocean color products of GLI and MODIS, 2) development of primary production algorithm, 3) showing usefulness of ocean color data for red tide monitoring, 4) showing usefulness of ocean color data for coastal environmental monitoring, and 5) establishing international collaborations. This study supported the product accuracy of GLI and MODIS, and supported the necessity of 250m ocean color data of Second-generation GLI (SGLI) on Global Change Observation Mission-Climate (GCOM-C). Furthermore, application of ocean color data was explored.
