"IBUKI" (GOSAT) Satellite's Historically Unprecedented Observation of Anthropogenic CO2 Emissions of Mega-City Regions from Space

The Greenhouse gases Observing SATellite "IBUKI", developed jointly by the Ministry of the Environment (MOE), the National Institute for Environmental Studies (NIES), and the Japan Aerospace Exploration Agency (JAXA) is the world's only satellite designed specifically to monitor greenhouse gases from space. The satellite has continued to fulfill its main mission in monitoring atmospheric carbon dioxide (CO2) and methane concentrations from space to improve the accuracy of sink/source estimates,...

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.
In 1997, the Kyoto Protocol was adopted at the Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3), making it mandatory for developed nations to reduce carbon dioxide emissions by six to eight per cent of their total emissions in 1990, and to meet this goal sometime between 2008 and 2012.
Furthermore, the Global Climate Observation System (GCOS) has been proposed by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) in order to strengthen observations of land, ocean, and space conducted by each country.

Launch date: January 23, 2009

Characteristics of Greenhouse gases Observing SATellite "IBUKI" (GOSAT)

Monitoring the distribution of the density of carbon dioxide, a Greenhouse gas.

So far, the number of ground-based carbon dioxide observation points has been limited, and they have been distributed unequally throughout the world. "IBUKI" will enable the precise monitoring of the density of carbon dioxide by combining global observation data sent from space with data obtained on land, and with simulation models.
In addition, observation of methane, another Greenhouse gas, has been considered.
