More than two years after road access and electrical power to the Mauna Loa Observatory was cut off by lava flows, NOAA staff continue to make critical measurements of the atmosphere and other environmental variables at the remote site.

In 2023, observatory staff installed solar panels at the site and resumed some measurements, including the independent carbon dioxide monitoring programs run by the Global Monitoring Laboratory and Scripps Institution of Oceanography, as well as other atmospheric measurements.

Construction of a temporary road to access the observatory site is anticipated to begin in summer 2025.

What does this program measure?

UV Index Plot
It measures temperature in Fahrenheit, wind direction in degrees, wind speed in mph, humidity in %, rain in inches, solar radiation in W m-2, and UV index.

How does this program work?

Solar Radiation Plot
A Davis Advantage pro plus weather station measures continuously at MLO, and data is made available at the MLO web site to the public (via internet). Click here to view today's Web Meteorology page.

Why is this research important?

Hourly Rain Plot
This system was set up for aiding staff and visitors on the conditions at the observatory site prior to arriving at the station by using a web browser.

Are there any trends in the data?
