Challenges to Accurate Measurement of Greenhouse Gases

In order to assess the increase or decrease of trace gases in the atmosphere that contribute to climate change including CO2 and methane, scientists first must determine accurate techniques that can be implemented at local, regional and global scales to monitor and verify transport of greenhouse gases. The author will explore some of the historical measurement challenges as well as current research at the National Institute of Standards and Technology to define uncertainty in measuring CO2,methane and other atmospheric greenhouse gases.
