AB: The long-term measurements of atmospheric CO2 concentrations at Mauna Loa Observatory provide an interesting test case for assessing the benefits and challenges of long-term earth observations. The Mauna Loa story illustrates how repetitive measurements can provide a rich opportunity for discovering new phenomena. As the CO2 records have continued to grow in length, important opportunities for discovery have continued to arise. Now spanning 50 years, the records are among the first places to turn for addressing certain questions relevant to future climate change, such as the detection of feedbacks of climate on CO2. This talk will provide a brief historical perspective on the challenges that were faced in sustaining the Mauna Loa CO2 record. Examples will be given to illustrate the continuing discovery process derived from the Mauna Loa and related records, and to illustrate the lessons learned in this process.
