★ [ACG09-28] Six-year-long GHG observation by GOSAT and three-year carbon flux estimation
Keywords:greenhouse gases, carbon dioxide, methane, column concentration, flux, GOSAT
In 2014, GOSAT went through some technical difficulties in the functioning of its solar paddle and sensor pointing mechanism, and the characteristics of the Fourier transform spectrometer onboard were therefore altered to some degree. The influence of this alteration on the retrieved concentrations has been detected.
In this presentation, we will summarize the six-year-long GHG observation by GOSAT and present the global distributions and variations of the GHG concentrations and the surface flux estimates. We will explain the changes in the characteristics of the GOSAT data products after June 2014 owing to the influence of the technical difficulties. Also, we will touch on the current status of researches conducted within the framework of the GOSAT Research Announcement.
