660 km above the Earth, GOSAT completes an orbit in approximately 100 minutes, measuring greenhouse gases at about 56,000 points on the surface. 15launch, they increasingly accepted the importance of monitoring the atmosphere from space as each new batch of data was analyzed. One after another, the U.S., Europe, China, and others launched their own observation satellites. All of these data are presently being made available to all scientists researching climate change and related topics. The next-generation observation satellite, GOSAT-2, measures CO2 with greater precision. Additions to the measurement wavelength region now make it possible to measure concentrations of CO. Akiko Suzuki, director of public relations at JAXA, explains, “To gain an accurate understanding of how the Earth is changing, it’s vital to collect this kind of observational data under identical conditions, to accumulate long-term, consistently reliable data. In this sense, the original GOSAT, which has taken continuous measurements for almost 10 years, has been a great success. With the cooperation of other countries, our goal is to continue to accumulate consistent measurements.” For the time being, both GOSAT and GOSAT-2 will continue to make observations assuming a two-satellite system. The data they obtain will be useful as scientific evidence for preserving the sustainability of our planet. Suzuki adds, “Our technology at JAXA keeps and use evolving through the development of observation satellites that get better at doing this. Going forword, we hope that we can contribute to a better world for all.”
