Atmospheric carbon dioxide (CO₂) and methane (CH₄) come from a variety of natural and anthropogenic sources and have a powerful global warming impact. Understanding the magnitude and distribution of these emissions spatially and temporally is critical to evaluating present and future climate impacts. Two trace molecules are often employed to investigate the relative importance of various sources (and sinks): d¹³C in CH₄ and d¹³C in CO₂. Biogenic sources of methane have lighter isotope ratios relative to thermogenic sources, although the ranges for each type of source are fairly broad and can overlap with each other.

In this webinar replay Felix Vogel (Researcher, LSCE) and David Kim-Hak (Product Manager, Picarro) will introduce you to identifying urban and industrial greenhouse gas sources using the Picarro G2201-i for best-in-class greenhouse gas (GHG) concentration and isotopic measurements.
