From ABC Rural:
"New technology is being rolled out across key cotton and grain growing regions to help prevent crop damage from spray drift as farmers face millions of dollars in losses.
"Spray drift is the airborne movement of agricultural chemicals outside a target area. Every cotton valley across Australia has been affected by moderate to severe spray drift incidents this year.
"After a lot of cases of spray drift damage in 2016, researchers at Cotton Research & Development Corporation and Grains Research & Development Corporation have been studying a specific weather phenomenon that can cause spray drift.
"They have developed a Weather and Networked Data (WAND) system to detect surface temperature inversion, which happens when a layer of cool, still air is trapped below warmer air close to the ground."
