Environmental Sensing

One of our goals at SDL is to resolve urban and rural air quality issues. In this area of research, we are particularly focused on aerosol and trace gas emissions. We are working on active projects involving agricultural air quality, particle and gaseous emissions of oil/gas producers, wind energy resource evaluation (wind prospecting), boundary layer meteorology, and chemical/biological defense.

We have an array of instruments that we use, including traditional point sensors, Fourier Transform Infrared (FTIR) spectrometry, and advanced remote sensing techniques such as lidar. Our mobile air quality research laboratory has been sent to a wide range of industrial and agricultural entities across the western United States.

Our team’s approach incorporates measurements from multiple scanning, standoff, and point sensors. Of particular interest is our scanning three-wavelength lidar (Aglite), which provides particulate size distribution and concentration density from laser backscatter measurements. Our broad network of point sensors aid in the validation and calibration of lidar measurements.

We are currently developing a technology called MPM-DIAL, which stands for Methane and Particle Measuring Differential Absorption Lidar. We are developing a MPM-DIAL sensor for the simultaneous detection of airborne particulates and methane gas. Our MPM-DIAL system will have a range of approximately 1 mile and have a spatial resolution of approximately 10 meters.

SDL is uniquely equipped to conduct research that develops the understanding of process management practices related to air quality. Our team’s measurement tools and skills, combined with our demonstrated field experience, provide a solid foundation for comparing different management practices.
