To improve accuracy of FY-4A measurements, NSMC will execute a new operational plan that makes the pre-scheduled China-area observations give way to the diffuse reflection calibration during the Autumn Equinox season. As a result, the China Area Imagery will not be available from CDAS at the following time:

(1)     6:45-7:00（Beijing Time）everyday in September 10 -19 

(2)     18:45-19:00（Beijing Time）everyday in September 20 - October 16

Hence this notification.
