Visit to Mauna Loa Observatory

Leave a comment

I just returned from the Hawaii International Conference on System Sciences (HICSS) on the Big Island.

While there, I decided to take an extra day to visit the Mauna Loa Observatory (MLO) located on the Mauna Loa Volcano.

As this is a research facility, I was fortunate to get access after contacting MLO Station Chief John Barnes (Thanks John).

Here’s me at 11,141 ft, chugging more air due to the reduced oxygen content.


MLO is an important baseline for atmospheric CO2 measurement and is home to the famous Keeling Curve (here’s an interesting historical account from the American Institute of Physics). Physical scientist Aidan Colton showed me the original Keeling instrument and described its operation (IR spectrophotometry: measurement of reflection or transmission properties of a material as a function of wavelength). Here it is:


Fast-forward to the digital age, and here’s the new equipment that is better-faster-cheaper:


In addition to C02, I also got a great overview of solar radiation monitoring. Thanks Ben and Greg.

Concentrations of greenhouse gas CO2 in the atmosphere are exceeding 400 parts per million (ppm) for the first time in human history. Given the connection between CO2 and global warming, we are entering uncharted waters for human life on earth.

We can’t all visit Mauna Loa to see CO2 measurement first-hand. But we can collaborate to find systemic ways to reduce CO2 emissions and make daily choices that are climate positive.
