Abstract

 The objective of this research is to verify the accuracy evaluation of the chlorophyll-a (Chl.a) product of the worlds first geostationary ocean color satellite "GOCI" which South Korea launched in 2010 using the MODIS data and survey data in inner bay. The GOCI / in-situ Chl.a data set is acquired during September, November, December, 2011 in Tokyo Bay. As a result of verification, the significant correlation was observed between "GOCI Chl.a and MODIS Chl.a" and "GOCI Chl.a and in-situ Chl.a", respectively (Relative errors are 43% and 41%, respectively). Moreover, if the GOCI data in Tokyo Bay is corrected from the expression of relationship between GOCI Chl.a and in-situ Chl.a, in the range of in-situ Chl.a which does not exceed 40 μg/l, it is well in agreement with time series change of Chl.a comparatively.
