Japan: Whole-atmosphere monthly mean carbon dioxide concentration, calculated by using data from world’s first satellite designed specifically for monitoring greenhouse gases from space, IBUKI, have been released to public. The satellite is jointly promoted by the Ministry of the Environment, Japan, the National Institute for Environmental Studies, and Japan Aerospace Exploration Agency.

The data reflected that CO2 levels in all layers of the atmosphere have reached 398.8 ppm in May 2015. It was also confirmed that the trend line of the whole-atmosphere CO2 mean, derived by removing averaged seasonal fluctuations from the monthly CO2 time series, had reached 398.2 ppm in July 2015. The trend line is expected to exceed 400 ppm within the year 2016, given that the rising trend continues.
