Following the switchover from GMS-5 to GOES-9, we show two images from two satellites as below. Those two satellites have slightly different characterstic in terms of sensor resolution and bandwidth, and the position of the geostationary satellite is far apart. Hence the direct comparison of images requires careful treatment. In addition, coherent noise is quite apparent on GOES-9 visible imagery, which indicates that the quality of GOES-9 sensors are lower than GMS-5 sensors.
