IBUKI methane observation data: close correlation between methane concentration and human activity
As a result of analyzing three-year observation data acquired by the Greenhouse Gas Observing Satellite “IBUKI” (GOSAT) until Dec. 2012, the concentration of methane is higher in areas where anthropogenically-derived methane emission is intense, such as densely populated areas, large-scale agricultural regions, natural gas and oil producing/refining areas, compared to other surround areas. In addition, intimate correlation was found between anthropogenically derived methane concentration o...
About Greenhouse gases Observing SATellite "IBUKI" (GOSAT)
"IBUKI": Global efforts to protect the environment.
Global warming has become a very serious issue for human beings. Scientists have suggested that, at the rate the Earth’s temperature is rising, an extreme form of global climate change could occur in a few centuries.
Launch date: January 23, 2009
Characteristics of Greenhouse gases Observing SATellite "IBUKI" (GOSAT)
Characteristics of greenhouse gas observation utilizing a satellite
The concentration of the greenhouse gases has been observed at observation sites on the ground and by aircrafts. However, there are only 348 sites (as of January 2013) and these sites place a disproportionate emphasis on a few areas. “IBUKI” is able to measure the concentration of greenhouse gases such as CO2 and CH4 over almost the entire surface of the earth at equal intervals every 3 days from the orbit traveling around the earth in approx. 100 minutes. This has made it possible to increase the observation points exponentially than before as well as obtaining the data over the region where we had no data until now. And it has been able to improve the estimation accuracy of the net flux of CO2 by up to 40% until now through the use of these data. The data obtained is anybody can use these data if they register as well as providing to governmental Institutions and scientists of various countries.
