Mauna Loa Observatory, Atmospheric research facility on Mauna Loa volcano, Hawaii County, United States.
Mauna Loa Observatory is an atmospheric research facility situated on a volcano in Hawaii that monitors air composition from a high-altitude location. The station measures gases such as carbon dioxide and methane in an environment far from cities and industrial pollution.
The facility was founded in 1956 and started measuring carbon dioxide levels shortly afterward. These early measurements established the foundation for tracking how Earth's atmosphere has changed over many decades.
This facility holds deep meaning in how the world understands climate change today. The measurements taken here shape conversations about environmental responsibility in countries and organizations worldwide.
The remote location at high altitude on an active volcano makes walking access challenging and requires advance planning. Visitors should prepare for cooler weather and wind, which are common at this elevation.
The measurements from this location create a continuous pattern showing how the atmosphere changes year after year. This pattern has become one of the most important tools for scientists to understand the state of our planet.
