Smooth air flow across the summit minimizes turbulence, helping keep images steady and increasing resolution compared to most other high altitude sites Predominant East-West air flow,
unobstructed by land for thousands of miles before it reaches Hawaii
High altitude dry air allows more infrared and microwave radiation to reach the summit
than lower elevations
Low Humidity
Diurnal inversion layer frequently caps cloud tops below the summit
Most of the Maunakea observatories have been
optimized to take advantage of these conditions
At night this inversion layer helps block city lights from below

Taking advantage of facility specialization, it is very common for discoveries made at one Maunakea observatory to be
followed up by observations at another to get a much more complete understanding of these objects…
