Shedding light on odor

A tool that’s been employed to hunt submarines and study clouds may change the way air is monitored around your dairy. That’s because LiDAR, short for Light Detection and Ranging, is a laser device that can pinpoint the location, distribution and nature of airborne particles.

It uses a radar-like technology that features short pulses of laser light to detect and differentiate airborne particles, gases or even molecules. The tool has been used in a number of ag applications, including a series of soil moisture experiments. And, recently, it’s been utilized to evaluate dispersion dynamics around swine facilities. So, don’t be surprised if it shows up on a dairy near you.
