Ranking of Agricultural Meteorological Stations

The ranking of agricultural meteorological stations should avoid special areas within orchards. Priority should be given to selecting the flat and unobstructed central area of the orchard to ensure that the monitoring data can represent the meteorological conditions of the entire orchard. Avoid the edges of the orchard, wind vents, low-lying areas, and near water sources, as these areas have special meteorological conditions that can easily lead to data bias. At the same time, it is necessary to avoid the obstruction of tall trees and buildings, to avoid affecting the monitoring accuracy of lighting, wind speed and direction. The distance between the sensor and surrounding obstacles should be greater than twice the height of the obstacles.
