How can the CWS655 readings be corrected for temperature?

There is not an easy way to correct CWS655 readings for temperature. The CWS655 temperature sensor is located inside the sensor’s epoxy head next to one of the sensor rods. The stainless-steel rods are not thermally conductive, causing the reported soil temperature reading to be the temperature of the sensor head near the soil surface. Because the sensor is installed vertically with the sensor head above ground, the soil temperature reading is not representative of the temperature over the length of the 12 cm rods, but the reading is closer to the temperature of the soil surface. Performing a temperature correction requires a separate temperature sensor to be buried at approximately 6 cm deep and combines that data with the values reported by the CWS655.
