Applications and Testbeds
We work to develop monitoring technologies and analysis methods to address key societal problems concerning air quality, regional climate, the carbon cycle, and public health.
* Air quality, regional climate, and carbon cycle assessments with focus on urban environments and energy production
* Laser therapy and surgery
* Medical diagnostics using breath analysis
* Field deployments of MIRTHE+ sensors
* Environmental – lidar, mobile sensor platforms, open path remote sensing, point sensors, turbulent flux measurements, wireless sensor networks
* Medical – clinical trials for fast response breath analysis

- Interdisciplinary Summer Research Project: The 2018 summer campaign performed by undergraduate and graduate students at Princeton University was an initial outdoor test of a methane sensing system developed for remote leak detection. A 50 m long sensor calibration facility was constructed to test the instrument with controlled methane mixtures and to provide a baseline performance of the instrument in terms of its accuracy and precision. The instrument was successfully tested to resolve single ppm concentrations of methane in atmospheric air with sufficient time resolution for observation of rapid methane concentration changes characteristic for localized pipeline leaks. Data obtained from the campaign will be used to improve both the instrument performance and the calibration facility to establish standardized outdoor testing procedures for remote trace-gas sensors. Further tests have been planned in the next few months.

- Vehicles, not farms, are likely source of smog-causing ammonia. Researchers found that ammonia emissions from cities are much larger than recognized, occur at the very times when unhealthy particulate matter is at its worst, and when agricultural emissions are at daily or seasonal lows.
