Study finds legacy emissions important to dairy production
The experiment leveraged remote sensing of ammonia by the hyperspectral remote sensing imager, Mako, to make maps of ammonia.
Animal husbandry produces the potent greenhouse gas, methane and ammonia. However, emission estimates vary widely with few real world studies. A recent NASA-supported study released by Bubbleology Research International (BRI), Goleta, Calif., combined remote sensing with advanced mobile analyzers to understand how differing husbandry practices vary within dairies, between dairies and between regions.
"We designed a holistic experiment to characterize emissions, including source identification by using multiple gases for fingerprinting," says Dr. Ira Leifer, chief scientist and CEO. "We acquired and analyzed data from satellite, airborne remote sensing, mobile surface in situ and mobile surface remote sensing."
