Over the past few months, I’ve had the privilege of working with collaborators from Penn State, Climmod, Sigma Space, NOAA and others to demonstrate the power of using high precision instruments coupled with advanced modeling techniques to measure greenhouse gas emissions in cities. While many cities are taking a step in the right direction by volunteering to report their emissions estimates, the self-reported numbers are only based on calculations, not on measurements of what is in the air.
