The Greenhouse Gases Observing Satellite (GOSAT), also known as Ibuki, is an Earth observation satellite and the world’s first satellite dedicated to greenhouse gas monitoring.

The GOSAT measures the densities of carbon dioxide and methane from 56,000 locations in the Earth’s atmosphere. The satellite was developed by the Japan Aerospace Exploration Agency (JAXA). Japan’s Ministry of the Environment and the National Institute for Environmental Studies (NIES) use the data to track gases causing the greenhouse effect and share the data with NASA and other international scientific organizations.

According to JAXA, the GOSAT is equipped with a greenhouse gas observation sensor (TANSO-FTS) and a cloud/aerosol sensor (TANSO-CAI) that supplements TANSO-FTS. The greenhouse gas observation sensor of Ibuki observes a wide range of wavelengths (near-infrared region–thermal infrared region) within the infrared band to enhance observation accuracy.

The satellite uses a spectrometer to measure different elements and compounds based on their response to certain types of light. This technology allows the satellite to measure “the concentration of greenhouse gases in the atmosphere at a super-high resolution.”
