Panchromatic all-sky TV data
Listed in NASA Earthdata CMR
This is a Sino-Japan collaborative observation at Zhongshan Station, Antarctica, which commenced in March 1995 (Principal Investigators: Prof.
Description
Natsuo Sato, National Institute of Polar Research and Dr. Huigne Yang, Polar Research Institute of China).
The observation system comprises a HARPICON (High-gain Avalanche Rushing Amorphous Photoconductor) TV camera fitted with a fish-eye lens. A HARPICON tube utilizes an amorphous photoconductive selenium target within which an avalanche signal multiplication may be obtained under a high voltage. The exposure time of the observation is set to 2 seconds and a sensitivity of ~6 times higher than that of a conventional SIT tube is achieved.

The all-sky TV data are originally recorded on video tapes in NTSC format, which are digitized into AVI files of 320*240 pixels.
