Ocean Theme: GODAE SST Project

GODAE has a fundamental dependence of SST dataand products
In particular, global perspective of GODAE demanded attention
to the many gaps in present products (many not quantified) andimproved representation of observational errors in data products

ADEOS-II SSTADEOS-II SST:
Combination of infrared,
microwave and in situ SSTs (1998)• GLI infrared SSTs:– High accuracy, fine spatial resolution, widecoverage• AMSR microwave SSTs:– Retrieval of SSTs under clouds, wide coverage• In situ SSTs:– Standard and reliable SSTs, anchor points forthe satellite SSTs
