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 meteorological, RoboDIMM´s atmospheric seeing graphs for a particular night (graphs cover a 24h range, starting at 09:00am), and links to other records of observing conditions.
