Greenhouse Gases Observing Satellite (GOSAT), also known asIbuki (Japanese:いぶき,Hepburn:Ibuki; meaning "breath"[4]), is anEarth observation satellite and the world's first satellite dedicated togreenhouse gas monitoring.[5] It measures the densities ofcarbon dioxide andmethane from 56,000 locations on theEarth's atmosphere.[6] The GOSAT was developed by the Japan Aerospace Exploration Agency (JAXA) and launched on 23 January 2009, from theTanegashima Space Center.[6] Japan'sMinistry of the Environment, and theNational Institute for Environmental Studies (NIES)[7] use the data to track gases causing thegreenhouse effect, and share the data withNASA and other international scientific organizations.[5]

Launch

[edit]

GOSAT was launched along with seven otherpiggyback probes using theH-IIA, Japan's primary large-scaleexpendable launch system, at 3:54 am on 23 January 2009 UTC onTanegashima, a small island in southern Japan, after a two-day delay due to unfavourable weather.[6][5] At approximately 16 minutes after liftoff, the separation of Ibuki from the launch rocket was confirmed.[8]

Instruments

[edit]

According to JAXA, the Ibuki satellite 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.[8] The satellite uses aspectrometer 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."[9]

GOSAT-2

[edit]

TheGreenhouse Gases Observing Satellite-2 was launched from Tanegashima Space Center by aH-IIA rocket on October 29, 2018.[10]
