Environmental Monitoring Of Gases Using Near-Infrared Diode Lasers
Southwest Sciences' researcher Chris Hovde in front of a prototype near-Infrared, diode laser instrument used for measuring methane fluxes. The Instrument combines rapid (10 Hz) measurements of methane concentrations with wind velocity to determine fluxes. An open-air, multiple-pass, optical cell allows ~40 ppb resolution in methane concentrations. The photograph was taken during-field measurements over Arctic tundra on the Alaskan North slope near Prudhoe Bay.
