The class drove through some urban streets in a van equipped with a GPS-linked methane analyzer. The height of the red spikes are proportional to measured methane concentrations. Lower left is near the MIT campus, with the so-called “Alps of Somerville” to the upper right. Image courtesy of Audrey Schulman / HEET.

Participants in this class drove through some urban streets in a van equipped with a GPS-linked methane analyzer, producing data and visualizations like this. The height of the red spikes are proportional to measured methane concentrations. Lower left is near the MIT campus, with the so-called “Alps of Somerville” to the upper right.
