GOSAT Project


GOSAT project is conducting research and development and data calibration and validation by using sensors onboard the “IBUKI” (GOSAT) series satellites for observing greenhouse gases (carbon dioxide, methane) which are the causes of global warming.

By onboarding a sensor on earth observation satellite, it is able to measure greenhouse gas distribution at more than 56,000 points on the earth and observe more than 100 times as many observation points placed around the world every three days.

JAXA is contributing to international efforts to combat global warming by monitoring the distribution and temporal changes of greenhouse gases on the globe and improving accuracy of estimating greenhouse gas emissions and estimating the sources of greenhouse gases emissions.
