Abstract
Imager (GOCI), the first pathfinder of ocean color remote sensing in
geostationary orbit from 2010, necessity of succession of GOCI mission after
the expected lifetime by 2018, is gradually increasing into the international
ocean color remote sensing users as well as domestic users in Korea.
As a successor of GOCI, development of GOCI-II has been started in 2012
with a planned launch in 2018. The mission and user requirements of
GOCI-II are defined by Korea Institute of Ocean Science and Technology
(KIOST) and international GOCI PI (Principal Investigators). GOCI-II will
be able to monitor the nearly full Earth disk area on 128.2˚E longitude in
geostationary orbit, and to acquire the local area(observation region can be
freely definable by user) image with 250m spatial resolution at nadir with 12
spectral bands from visible to NIR (370~885nm). These enhanced features
will enable the monitoring and research of long-term ocean environment
change with better image quality. Additional 4 spectral bands are added to
improve the accuracy of data products such as chlorophyll concentration,
total suspended sediments, dissolved organic matters, enhancement
of atmospheric correction, and to have a novel capability such as PFT
(Phytoplankton Functional Type) which enables to discriminate harmful
algae bloom. Newly implemented panchromatic band with 402~885nm
bandwidth is expected to enable star imaging for themote sensing users as well as domestic users in Korea.
