For information on details on the image data, see data description, the original Zenodo record and the provided literature. A journal article describing the network and dataset has been submitted and will be provided as soon as available.

File and directory structure

Raw images are zipped per day and station in asi/imgs/{YYYY}/{mm}/{dd}/

with YYYY=Year, mmm=month, dd=day

Filenames have the format ASI_{YYYYmmdd}_{STATION}.zip

with STATION=station id

Meta data is stored in asi/meta/{STATION}/

For downloading multiple zip-files a bash-script and a python-script are provided in data download
