In this episode, Dr. Sean Crowell interviews Dr. Caroline Alden, the Chief Science Officer of Long Path. Long Path is an advanced methane monitoring startup with a simple goal: provide continuous monitoring of upstream oil & gas facilities to improve operations and lower methane emissions. They accomplish this goal using a high precision laser absorption spectrometer to create a "laser fence line monitor" around potential emission sources.

Have a listen to hear about Caroline's transition from carbon cycle scientist studying isotopes to the exciting world of an environmental monitoring startup.

How do you detect methane leaks from space? And once you do - what comes next?
In this episode, Dr. Ilse Aben shares the story of TROPOMI, the Dutch-led satellite instrument that scans the Earth daily for greenhouse gases. We explore how column measurements are turned into emissions, the power of'tip-and-cue' collaboration with commercial satellites, and how UN-backed systems are turning satellite data into climate action on the ground.
