Atmosphere methane concentration retrieving with the help of infrared LEDs

Abstract: Nowadays the application of IR LEDs (light emitting diode) for measuring atmospheric gas concentration is a topic which is not studied profound enough. The main feature of applying such a light emitters is that the radiation band is very broad (from 10 to 100 cm –1 ). Spectral broadband of a emitter and the receiver lead to the influence of other gases of an atmosphere absorption that effects on accuracy of the inverse task. The article presents a description of a technique and results of numerical modeling of a methane concentration retrieving with the help of a gas analyzer on the basis of infrared LEDs.

Keywords: atmospheric methane, leds, methods for processing and analysis
