Weather Station Maintenance Guidelines Inspect your weather
station at least twice per year to make sure all sensors are
clean, free of debris and in good working condition. Inspect
mounting brackets, poles, posts, etc. to make certain they are
stable, vertical and sound and the instrument is securely
fastened. Protect weather instruments, sensors and cables from
pruning, spraying and harvesting activities that may damage the
sensors, cut cables, or cause weather stations to lean.
Temperature and relative humidity sensors: Temperature sensors
are delicate instruments that should be periodically checked,
usually once per year or according to the manufacturers
recommendation, to make certain they are accurate. Compare the
readings of the weather station sensors with a calibrated
thermometer or with another nearby weather station. Dry bulb
temperature sensors record temperature. Wet bulb temperature
sensors record dew point temperature from which relative
humidity (RH) is calculated. Precipitation (rain) gauges:
