Watch your breath megacities: Project aims to track greenhouse gases from LA, Paris - ktuu.com
This summer, technicians will install commercial gas analyzers at a dozen more rooftops around the greater LA region. Scientists also plan to drive around the city in a Prius outfitted with a portable emission-measuring device and fly a research aircraft to pinpoint methane hotspots from the sky. (A well-known natural source is the La Brea Tar Pits in the heart of LA where underground bacteria burp bubbles of methane gas to the surface.)
Launching the monitoring project came with the usual growing pains. In Paris, a carbon sniffer originally tucked away in the Eiffel Tower's observation deck had to be moved to a higher floor that's off-limits to the public after tourists' exhaling interfered with the data.
So far, $3 million have been spent on the U.S. effort with funding from federal, state and private groups.
