The Mauna Loa Solar Observatory (MLSO) is happy to announce the initial release of a web service API for searching and downloading our data and invites the community to use it for programmatic access to our data. Currently data from the K-Coronagraph (KCor) and Upgraded COronal Multi-channel Polarimeter (UCoMP) are available, with data from additional instruments to be added in the future. Various search filters based on date/time and instrument specific attributes are supported, including filters to retrieve data on a regular time cadence, e.g., one file of a specific type every day, every hour, etc.
Convenience bindings for Python, IDL, and the command-line are provided, though the API is usable from any language with the ability to make HTTP requests, including a web browser, curl, or wget. The source code for the clients is available via GitHub.
For more information see the MLSO API web page or the documentation.
