Soil moisture profiles were meaured at the BCSE with several techniques. Initially we installed a TDR array at 7 depths. In 2019 we installed a set of campbell CS650 probes at 3 depth in a subset of the plots. original data source http://lter.kbs.msu.edu/datasets/173

The hourly data is passed through a 13 point median filter, then the daily median is retrieved and the result is passed through a 3 point filter that passes the middle point if the vwc is within 0.03 % of the mean of the surrounding points if it did not rain in the last 2 days. If it did rain it middle point is accepted if it is higher than the mean of the outside points.Soil+profile+moisture.csvNone271\ncolumn,no"\https://data.sustainability.glbrc.org/datatables/563.csvsample_dateThe sample dateYYYY-MM-DD11987-4-18siteThe experimental siteThe experimental siteexperimentThe experiementThe experiementtreatmentthe treatmentthe treatmentreplicatethe replicate plotthe replicate plotsoil_depth_cmthe soil depth where the moisture is measuredcentimeterrealvolumetric_soil_moisturethe fractional volumetric soil moisturecubicMeterPerCubicMeterrealyearthe year where the sample was takenintegerhttps://lter.kbs.msu.edu/datatables/795Kellogg Biological Station LTER: Soil moisture profiles in replicate 1 of the BCSE (GLBRC123_002)Soil moisture is measured with Campbell CS650 soil moisture probes (https://www.campbellsci.com/cs650) in Replicate 1 of the BCSE.
