MLO is located 11,135 feet above sea level on the Big Island of Hawaii.

Why do you think the Mauna Loa Observatory’s location is ideal for monitoring Earth’s atmosphere?
Question 1 options:

The location of the research center allows scientists to measure the effects volcanoes have on carbon dioxide levels released from nearby volcanoes.

The location is near a heavily populated area and it serves as a baseline for detecting pollution in major cities.

The remote location allows scientists to measure baseline atmospheric data without being influenced by a local pollution source.
