[Phys-L] Infrared

["Forinash III, Kyle" <kforinas@iu.edu>]

I’m a bit confused by the following New York Times article. They claim to be detecting methane leaks using IR cameras in the 3.2 to 3.4 Micrometer range. Wouldn’t such an image be overwhelmed by thermal IR? In other words the pictures are of heat, not methane specifically?
