Of SurfACe TemPerATure SPrAy OPerATiOnS in cooling night conditions airborne pesticides can concentrate near the surface and unpredictable winds can move droplets away from the target... During surface temperature inversions, air near the ground lacks turbulence... SOurCe GrAeme TePPer under a surface temperature inversion: air movement is much less turbulent so the air does not mix in the same way as during the day; airborne droplets can remain concentrated in the inversion layer for long periods of time; the direction and distance pesticides movement is very hard to predict; the movement of airborne droplets will vary depending on the landscape; and droplets or their remnants can move in different ways (figure 3)...
