Technical Interface Meeting over IBUKI observation data

Between November 10 (Tue.) and 13 (Fri.), a GOSAT-ACOS* technical interface meeting is being held at the JAXA Tsukuba Space Center and at the National Institute for Environmental Studies. In the meeting, we are discussing the calibration and verification of observation data acquired by the IBUKI to improve data accuracy so as to be ready for the distribution of density data to the general public that is scheduled to start in January 2010.

*The ACOS (Atmospheric CO2 Observations from Space ) Team is in charge of analyzing IBUKI observation data. The team is formed by a number of institutions including the NASA Jet Propulsion Laboratory (JPL), the California Institute of Technology (Caltech), and Colorado State University.

Overview

"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.


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.
