Abstract: A system configured to provide output indicative of crop spraying conditions in an agricultural region, the system including: an input configured to receive data from at least one monitoring physical tower, wherein the physical tower extends from ground level in the agricultural region, wherein the tower includes one or more anemometers configured to measure respective wind speeds at one or more predetermined heights above the ground level; a processor which is configured to process periodic values of respective wind speeds at the one or more predetermined heights above the ground level, thereby to derive a real-time measure representative of a local vertical turbulence characteristic for the location of the monitoring tower, wherein the real-time measure representative of a local vertical turbulence characteristic for the location of the monitoring tower is based on a standard deviation of vertical wind speed; and an output device which is configured to provide the output indicative of crop spraying conditio

Abstract: Systems and methods are for determining and/or forecasting local atmospheric stability and/or turbulence. This information can be used to inform decisions regarding crop spraying, such as whether the atmospheric conditions are sufficiently turbulent to avoid airborne spray fines drifting in an undesirable manner. For example, a spray drift hazard alert system can include a data logger. The data logger is configured to: receive local meteorological observation data from one or more sensors at a location, analyze the data to determine a local vertical turbulence characteristic indicative of a current level of vertical turbulence at the location, compare the vertical turbulence characteristic with a predetermined threshold of the vertical turbulence characteristic, and transmit information to a client device indicating whether local meteorological conditions are suitable for crop spraying based on the comparison between the vertical turbulence characteristic and the predetermined threshold.
