Lunar Simultaneous Observation Inter-comparison from FY-3D and Ground-base Lu Zhang, Peng Zhang , Xiuqing Hu, Na Xu, Lin Chen,Ronghua Wu National Satellite Meteorological Center NSMC 1st International Strategic Consultative Discussion on Chinese Meteorological Satellite, 18,Nov, Outline Background MERSI-II/FY-3D and Ground-base equipment

Methodology Result Future work NSMC 1/31/20 2 / Background Grant had compared Japans Geostationary Meteorological Satellite (GMS-5) and ROLO nearly simultaneously. Li Jiang Ground-base observation compared with MERSI-II/FY3D.
