Interpretive Summary:

Technical Abstract: Data discontinuities from soil moisture sensor replacement can be mitigated by intercalibration. We used 154 pairs of sensors from the Marena, Oklahoma, In Situ Sensor Testbed (MOISST) to assess if there is a minimum amount of overlapping data required for the intercalibration process. Periods ranging from 1 month to 2 years were considered. The results indicate that a minimum of 6-9 months between installing the new sensor and decommissioning the old is necessary to generate a successful intercalibration. Our recommendation is to extend that overlap to a full year for higher confidence.
