Automated in situ soil sensor network - the data set includes hourly and daily measurements of volumetric water content, soil temperature, and bulk electrical conductivity, collected at 42 monitoring locations and 5 depths (30, 60, 90, 120, and 150 cm) across Cook Agronomy Farm. Data collection was initiated in April 2007 and is ongoing.
\nCAF_sensors: folder with Daily and Hourly subfolders, each containing 42 '.txt' files of water content and temperature sensor readings.\nEach file represents readings from a single location, indicated in the file name (i.e. CAF003.txt) and in the 'Location' field of the table.\nReadings are organized by 'Date' (4/20/2007 - 6/16/2016), \u2018Time\u2019 (24 hr clock, only in hourly files), and with property (VW or T) and sensor 'Depth' as follows:
\nVolumetric water content readings are calibrated according to:\nGasch, CK, DJ Brown, ES Brooks, M Yourek, M Poggio, DR Cobos, CS Campbell. 2017. A pragmatic, automated approach for retroactive calibration\nof soil moisture sensors using a two-step, soil specific correction. Computers and Electronics in Agriculture, 137: 29-40.\nTemperature readings are factory calibrated.
\nCAF_BulkDensity.txt: file containing bulk density values ('BulkDensity' in g/cm^3) for sensor depths at each of the 42 instrumented\nlocations at Cook Farm. Location is indicated in 'Location' field, and sample depths are defined (in cm) by the \u2019Depth\u2019 field.
\nCAF_CropID.txt: file containing crop codes for each sub-field (A, B and C) and strip (1-6 for A and B, 1-8 for C) at Cook Farm for 2007-2016.\nThis is also part of the attribute table for 'CAF_strips.shp'
\nCAF_CropCodes.txt: file containing crop code names and crop identities, used in 'CAF_CropID.txt' and 'CAF_strips.shp'
\nCAF_ParticleSize.txt: file containing particle size fractions ('Sand', 'Silt', and 'Clay' as percent) for each 'Location' at sensor depths\n('Depth', in cm).
\nAll spatial data have spatial reference NAD83, UTM11N
\nCAF_sensors.shp: file containing locations of each of the 42 monitoring locations, the 'Location' field contains the location name,\nwhich coincides with locations in tabular files.
\nCAF_strips.shp: file containing areal extents of each sub-field, stip, and crop identities for 2007-2016. Crop identity codes are listed\nin 'CAF_CropCodes.txt'
\nCAF_DEM.tif: file containing a 10 x 10 m elevation (in m) grid for Cook Farm.
\nCAF_Spring_ECa.tif, CAF_Fall_ECa.tif: files containing 10 x 10 m apparent electrical conductivity (dS/m) grids to 1.5 m depth for spring\nand fall at Cook Farm.
\nCAF_Bt_30cm.tif, CAF_Bt_60cm.tif, CAF_Bt_90cm.tif, CAF_Bt_120cm.tif, CAF_Bt_150cm.tif: files containing 10 x 10 m predictive surfaces for\nprobability (0-1) of Bt horizon at the five sensor depths.
\nThe Flags folder consists of the files containing the quality control flags for the Cook Farm Sensor Dataset.
\nThe nomenclature for the files indicates flags for either temperature (T) or water content (VW) and sensor depths. For example:
\nFiles starting with \u201cmissing\u201d contain flags (\u201cM\u201d) for locations and dates (mm/dd/yyyy) with missing data (NA in original dataset).
\nFiles starting with \u201crange\u201d contain flags for locations and dates (mm/dd/yyyy) with values outside acceptable ranges:
\nFiles starting with the name \u201cflats\u201d contain flags (\u201cD\u201d) for locations, dates (mm/dd/yyyy), and times (hh:mm) with constant values (within 1%) for a 24 hour period, as in Dorigo et al. 2013.
\nFiles starting with the name \u201cspikes\u201d contain flags (\u201cD\u201d) for locations, dates (mm/dd/yyy), and times (hh:mm) with sudden spikes in VWC readings.
\nFiles starting with the name \u201cbreaks\u201d contain flags (\u201cD\u201d) for locations, dates (mm/dd/yyy), and times (hh:mm) with sudden breaks (jumps or drops) in VWC readings.
\nCode (implemented in R) for the screening and flagging is included in \u201cCode Snippet.txt\u201d
