GOSAT 2 (Ibuki 2)


GOSAT 2 (Greenhouse Gases Observing Satellite 2) is JAXA's next generation satellite to monitor the greenhosue gases like carbon dioxide in the Earth's atmosphere. It is the follow on to the GOSAT (Ibuki) mission.

It will monitor the greenhouse gases carbon dioxide, methane, carbon monoxide with increased accuracy to continue and improve GOSATs work. The observation accuracy is 0.5 ppm for carbon dioxide and 5 ppb for methane at a 500-km mesh over land.

GOSAT 2 features two instruments:

  • Thermal And Near Infrared Sensor for carbon Observation - Fourier Transform Spectrometer (TANSO-FTS)
  • Thermal And Near Infrared Sensor for carbon Observation - Cloud and Aerosol Imager (TANSO-CAI-2)

In December 2013, Mitsubishi Electric (MELCO) was selected as the prime contractor for the spacecraft and the instruments.
