Future work

3. Background
Grant had compared Japan‘s Geostationary Meteorological Satellite (GMS-5) and ROLO nearly simultaneously.
Li Jiang Ground-base observation compared with MERSI-II/FY3D.
Lunar calibration of geostationary visible-band imagers, Grant, I. F.; Kieffer, H. H.; Anderson, J. M.,SPIE,1998, 337-34

4. Background

5. Background Atmospheric effects remove (a) (b)
Blue line is MT2009 model，Red line is Earth based observation，Black line is ROLO model. In the figure (a) , the red dashed line is Earth based observation not remove the atmospheric effects. In the figure (b) , the red line is Earth based observation removed the atmospheric effects, T12:59:34 ）

6. Background
The Bands for FY-3D/MERSI inter-comparison: 1-4 band,8-19 band.
The uncertainty of FY-3D/MERSI prelaunch is ~5%.

7. Methodology Select lunar observation both MERSI/FY3D and ground-base
The near Simultaneously observation
The less different of observation geometry
The time of FY3D and ground-base observation of lunar:

T12:16: T18:48:17

8. Methodology
the observation geometry(FY3D):

9. Methodology
the observation geometry(ground-base):

10. Result The FY3D: 2017-11-30T08:42:27,Ground-base:2017-11-30T12:13:19
Observation geometry:
Ob-Selen- Lat Ob-Selen- Lon Solar -Selen-Lon Phase
Ground-base:
FY3D:

11. Future work Simultaneously Different observation geometry
Not at the same time
Almost same observation geometry
