The Greenhouse Gases Observing Satellite ( GOSAT ), also known as Ibuki in Japanese ( い ぶ d, English "breath; breath"), is an earth observation satellite and the first satellite to be used to monitor greenhouse gases . It measures the distribution of carbon dioxide and methane at 56,000 points in the earth's atmosphere . GOSAT was designed by the Japanese space agency JAXA and launched on January 23, 2009 from the Tanegashima Space Center with an H-IIA . So far there are only 282 land-based CO 2 measuring points (as of October 2008), the largest number of which are in the USA, Europe or other industrialized nations.

The measurements are carried out with the TANSO measuring device. TANSO stands for "Thermal and Near infrared Sensor for Carbon Observation". The measuring device consists of the modules TANSO-FTS and TANSO-CAI. FTS stands for “Fourier Transform Spectrometer”, CAI stands for “Cloud and Aerosol Imager”.

The TANSO-FTS, based on the Michelson interferometer , allows the concentration of the greenhouse gases CO 2 , CH 4 and H 2 O to be determined using spectral measurements on four frequency bands .

With the help of the TENSO-CAI, the thickness and degree of coverage by clouds and aerosols are determined in order to eliminate measurement errors of the TANSO-FTS.

For Ibuki a period of five years was planned. In 2014, the mission was extended by four years and the successor satellite GOSAT 2 was launched on October 29, 2018 . In May 2019 it was announced that EUMETSAT and JAXA will cooperate for future measurements.

The spacecraft and its payload are operating nominally. With a nominal design life of 5 years and the good health of the spacecraft, the mission life was extended (by JAXA, NIES and MOE) for another 4 years (a contract was signed with the same operations team).
