ABOUT

 Since 2009, the Greenhouse gases Observing SATellite (GOSAT) has been observing greenhouse gases from space. In this research, JAXA has applied the remote sensing technology with the spectrometer onboard GOSAT to passenger aircrafts operated by ANA. Since October 2020 we have measured horizontal distribution of atmospheric compositions such as carbon dioxide (CO2) and nitrogen dioxide (NO2) over megacities and plant sun-induced chlorophyll fluorescence (SIF) with much higher spatial resolution from the upper sky. We will estimate local emissions from different source sectors such as power plants, industries and transport by combining the satellite data and results by this study.
 We first acquired data by regular flights between Tokyo Haneda and Fukuoka city. In the future, we will provide emission data over urban areas, where are responsible for more than 70% of global total greenhouse gases emission. We aim to contribute to the Paris Agreement by presenting reduction effects from different source sectors.
