Brian Kirk Hornbuckle

About

I am an agronomist, a scientist who works to understand how crops and cropping systems can be used to provide humans with food, feed for livestock, fiber, fuel, and fossil-fuel replacements. My specific expertise is in agricultural meteorology, which can be roughly defined as the study of how cropping systems are affected by weather and climate, and how cropping systems themselves affect weather and climate. I use remote sensing to understand and quantify the movement of water among the soil, crop canopy, and atmosphere. I teach environmental physics to both undergraduate and graduate students and I am the director of graduate education for Iowa State's agricultural meteorology program.
