Assignee: THE WESTERN AUSTRALIAN AGRICULTURE AUTHORITY
Field: Measurement (Instruments)
Classification: CPC G  A  Y | IPC G

Claim 10:
11. A system configured to deliver a sensory alert indicative of crop spraying conditions in an agricultural region independent of inversion conditions as measured by vertical temperature difference, the system including:
at least one monitoring physical tower which extends from ground level in the agricultural region, wherein the tower includes one or more anemometers configured to measure respective wind speeds at a predetermined heights above the ground level, wherein the one or more anemometers include at least one 3D anemometer configured to measure three-dimensional wind speed components;
a processor which is configured to process periodic values of respective wind speeds at a 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 at the agricultural location; and
an output which is configured to provide the sensory alert indicative of crop spraying conditions independent of inversion conditions based on a comparison between: (i) the real-time measure representative of the local vertical turbulence characteristic; and (ii) one or more predetermined threshold values.
