Husbandry trace gases that have climate change implications such as carbon dioxide (CO), methane (CH) and ammonia (NH) can be quantified through remote sensing; however, many husbandry gases with health implications such as hydrogen sulfide (HS), cannot. This pilot study demonstrates an approach to derive HS concentrations by coupling in situ and remote sensing data. Using AMOG (AutoMObile trace Gas) Surveyor, a mobile air quality and meteorology laboratory, we measured in situ concentrations of CH, CO, NH, HS, and wind at a southern California university research dairy.

MISTIR reference flux validated AMOG plume inversions at different information levels including multiple gases, GoogleEarth imagery, and airborne trace gas remote sensing data. Long-term (9-yr.

Both have important spectral features in the Thermal InfraRed (TIR) that can be studied by remote sensing, with NH allowing discrimination of husbandry from other CH sources. Airborne hyperspectral imagery was collected for the Chino Dairy Complex in the Los Angeles Basin as well as in situ CH, carbon dioxide (CO) and NH data.
