The mission of the GOSAT-2 projectMission

 

The increase of the atmospheric concentration of greenhouse gases such as carbon dioxide (CO2) and methane (CH4) is thought to be one of the major factors affecting the earth's climate and various activities to monitor concentrations of these gases have been conducted in many countries. However, the geographical inhomogeneity and lack of greenhouse gas measurement stations are ongoing cause of the large uncertainty in the estimated fluxes of these gases.

 

GOSAT (Greenhouse gases Observing SATellite) is a Japanese satellite dedicated to greenhouse gas measurement from space, launched in January 2009, and which has been obtaining global CO2 and CH4 concentration data for more than eight years. Many scientists from more than 20 countries are using GOSAT data in their research and publish their original results to science communities.

 

GOSAT-2 (Greenhouse gases Observing SATellite 2) is a successor to GOSAT and will be launched in FY2018 with a design lifetime of 5 years.

 

The missions of GOSAT-2 are: 

  1. to continue and enhance spaceborne measurement of major greenhouse gases from space started by GOSAT,
  2. to monitor the impacts of climate change and human activities on the carbon cycle, and
  3. to contribute to climate science and climate change related policies.
