Abstract
GOSAT-2 project retrieve and estimate the global concentration distribution of major greenhouse gases including the sources and natural absorbers with high level of accuracy to contribute to environmental administration as follows.
– Improved precision of climate change predictions
– Early detection of changes in the Earth system
– Better understanding of emission reduction level of the anthropogenic greenhouse gases and changing natural sink
– Contribution to air pollution monitoring policies
Also, GOSAT-2 project researches and develops new earth observation technologies required for future earth observing satellites.
