Measurements at NOAA's Mauna Loa Observatory stopped following the recent eruption of the Mauna Loa volcano, when lava flow blocked staff access and took out power lines to the facility.

Under an emergency agreement, NOAA and the University of Hawaii have established a temporary measurement site at the nearby Mauna Kea volcano for the critical CO2 record and other atmospheric measurements taken at the observatory.
