GOSAT – Greenhouse Gas Observing Satellite (Ibuki) is a groundbreaking solution that revolutionizes the monitoring and tracking of greenhouse gas emissions on a global scale. Launched in January 2009, GOSAT, also known as Ibuki, is the world’s first satellite dedicated to greenhouse gas monitoring. It utilizes advanced infrared Fourier transform spectrometry to measure CO₂ and CH₄ concentrations across Earth’s atmosphere with exceptional precision.

With over 56,000 locations covered, GOSAT provides high-resolution, global data that offers daily, consistent measurements of greenhouse gas concentrations. This data is instrumental in identifying emissions sources and sinks, including industrial areas, forests, and oceans. The information gathered by GOSAT is utilized by Japan’s Ministry of the Environment, National Institute for Environmental Studies, NASA, and other international partners to support climate modeling, policy-making, and emissions verification protocols.

GOSAT’s continuous operation over the years has been crucial in climate monitoring efforts and has played a significant role in informing sustainable environmental strategies. The upcoming successor, GOSAT‑GW, set to be launched in 2025, will further enhance capabilities by providing higher resolution and broader coverage of greenhouse gases. By converting invisible emissions into actionable data, GOSAT is a key player in global initiatives aimed at managing climate change and promoting environmental resilience.
