Observatory Operations - All Sky Imager Data from the Australian Antarctic Territory and Macquarie Island
Entry ID: ASAC_527_allsky

Abstract: All Sky Imager Systems (ASIS) are deployed at Casey, Davis, Macquarie island and Mawson. These systems are autonomous data collection systems which record All Sky Imager data during periods of darkness at the stations.

The data are collected using a monochromatic video camera fitted with an Image Intensifer and a Fish eye lens. A filter (normally 558 nm) is also fitted to the cameras. (this can ... View entire text

Quality All Sky Imager Data
Data are recorded with a timing accuracy of +/- 1 second. Typical time resolution is 1 frame per 30 seconds although this can be interpreted from the time stamps on each frame.

Every frame has the following information stamped in the corners:
- Station Name
- UTC Time
- Day Number
- Year Number
- Exposure Time
- Filter Wavelength

In addition, each file contains preface frames giving latitude and longitude as well as orientation information.
Access Constraints Data are available for use in research activities provided consent of, and suitable reference to experiments and principal investigator is given.

Data stored as video and image files (mpeg and jpeg).

Data are available in nightly MPEG files and are typically between 10 Mbytes and 60 Mbytes in length depending on the time of year.

Owing to the amount of data, these files are stored on the ATMOS server at the Australian Antarctic Division. Contact the AADC to access the data.
