[76.09] The SOLIS Data Handling And Archive System

F. Hill, B. Goodrich, S. Wampler (NSO/NOAO), SOLIS Team

The Synoptic Optical Long-term Investigation of the Sun (SOLIS) project at NSO will replace the Kitt Peak Vacuum Telescope with a suite of state-of-the-art observing instruments. These instruments, comprising a Vector Spectromagnetograph (VSM), a Full-Disk Patrol (FDP), and an Integrated Sunlight Spectrometer (ISS), will provide a 25-year record of synoptic solar observations. In this poster we describe the systems that a typical user will be most concerned with -- the data handling and archiving systems.

The current design separates the reduction of the SOLIS data from the archiving. In this design, the reduction will be performed at the observing site on Kitt Peak using distributed work stations, RAIDs, and a storage area network. The reduced data will be transmitted via a DS3 link to the archive located in the NOAO headquarters in downtown Tucson. Quick-look calibrated data will be available over the web within 10 minutes of acquisition.

The current archive design comprises two servers, a RAID, a high-capacity tape jukebox, and several optical-disk jukeboxes. A portion of the core synoptic science program will be permanently held on-line. Some of the data products that will be available are 3-per-day photospheric vector magnetograms, chromospheric line-of-sight magnetograms, and He I 10830 quantities; 1-per-10-minute H-alpha, He I 10830, continuum and Ca K images; and 60 disk-integrated solar spectra per day. Users will be able to search and download this data in a manner similar to the current NSO Digital Library. Additional core synoptic data (e.g. 1-per-minute H-alpha and He I 10830 images) will be in near-line tape storage, while PI data will be distributed via high-capacity tapes.
