We currently offer the following past meterological data obtained using the ING weather stations and RoboDIMM:

• The Historical Graph Archive, which shows both short and long term variations of many meterological and telescope specific parameters. Enter the historical graph archive.
• The Night-to-Night Archive, which contain detailed meterological and RoboDIMM's atmospheric seeing graphs for a particular night. Graphs cover a 24h range, starting at 09:00am.
