This dimension groups observatories by the year they began operating. Wikipedia notes that observatories have long been built for disciplines including "astronomy, climatology/meteorology, geophysics, oceanography and volcanology," with new instruments continually replacing older ones as technology improves. Browsing by operational start year lets a visitor compare observatories that came online in the same period.
