This work was funded by the National Science Foundation. New Infrared Light Sources for Spectroscopy and Gas Sensing Applications Southwest Sciences is currently collaborating with Prof. Ravi Jain, The University of New Mexico, and Dr. Nigel Cockroft , Los Alamos National Laboratory, in the development and testing of new tunable infrared light sources for laboratory spectroscopy and gas sensing applications. Alan Stanton or David Bomse 2. Airborne Humidity Measurements Southwest Sciences has developed several diode laser-based instruments for airborne measurement of humidity. Diode laser-based detection of H 2 O provides a combination of high sensitivity, rapid time response, and wide dynamic range that is superior to most other available methods for humidity measurement.
Current efforts focus on development of instrumentation for use on unmanned aerial vehicles.
With funding from the Department of Energy, San Diego State University, and the NASA Ames Research Center , we have developed diode laser-based instrumentation for measurement of methane flux from natural and manmade sources. Our current efforts are focusing on reducing the cost of this type of instrumentation by development of new, customized digital signal processing methods and implementation of a novel multiple pass optical design that uses very inexpensive mirrors.

Current experiments are aimed at extending these measurements to molecular oxygen, but using an optical scanning system to obtain substantially improved spatial resolution.
