Dr. L. Larrabee Strow, Research Professor, is a member of the science team for the satellite IBUKI launched from Japan on January 23rd. IBUKI (also known as the Greenhouse Gases Observing Satellite, GOSAT) is a Japanese mission designed to map the abundance of greenhouse gases in the atmosphere. During its five-year mission it will identify and monitor sources of CO2 in support compliance with international treaties and agreements such as Kyoto. So far, the number of ground-based CO2 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 simulations. “Synergy between IBUKI/GOSAT and my recent work on global CO2 trends using NASA's AIRS satellite instrument”, said Dr. Strow, “should improve both instruments unique view of global greenhouse gases. The very international nature of the IBUKI/GOSAT Science Team has already provided me with new collaborations in this politically relevant field of science."
