Abstract
Data file descriptions for Cook Farm sensor network data set (CAF_Sensor_Dataset). This is a companion data set for: "Gasch, CK, Brown, DJ, Brooks, ES, Campbell, CS, Cobos, DR, Chahal, M, Poggio, M, Huggins, D.R. In preparation. A field-scale sensor" network data set for monitoring and modeling the spatial and temporal variation of soil moisture in a dryland agricultural field. "Anticipated submission to Water Resources Research, December 2015." All methods for data collection are described in detail in the text of this manuscript. "Data set compiled by Caley Gasch, Department of Crop and Soil Sciences, Washington State University, Pullman, WA. caley.gasch@wsu.edu" Updated: 10/27/2015 Tabular data: "CAF_VWC: folder containing 32 '.txt' files of water content sensor readings. Each file represents readings from a single location," indicated in the file name (i.e. CAF007_vwc.txt) and in the 'Location' field of the table. Readings are organized by daily 'Date' (4/20/2007 - "9/30/2014), and sensor 'Depth' as follows:" VW_30cm: sensor readings at 30 cm depth VW_60cm: sensor readings at 60 cm depth VW_90cm: sensor readings at 90 cm depth VW_120cm: sensor readings at 120 cm depth VW_150cm: sensor readings at 150 cm depth All readings are in units m^3/m^3. Raw sensor readings are calibrated in situ using a method described in: "Gasck, CK, Brown, DJ, Brooks, ES, Yourek, M, Poggio, M, Cobos, DR, Campbell, CS. In review. Retroactive calibration of soil moisture" "sensors using a two-step, soil-specific correction. Submitted to Vadose Zone Journal, September 2015." *** 10 additional locations are instrumented but are currently missing data. These locations will be uploaded when data processing "is complete (anticipated in November). Thus, this folder will eventually contain a total of 42 files. Additionally, all files will" be updated to include readings from the period 4/20/2007 - 12/31/2014. *** "CAF_Temp: folder containing 42 '.txt' files of soil temperature sensor readings. Each file represents readings from a single location," indicated in the file name (i.e. CAF007_temp.txt) and in the 'Location' field of the table. Readings are organized by daily 'Date' (4/20/2007 - "9/30/2014), and sensor 'Depth' as follows:" Temp_30cm: sensor readings at 30 cm depth Temp_60cm: sensor readings at 60 cm depth Temp_90cm: sensor readings at 90 cm depth Temp_120cm: sensor readings at 120 cm depth Temp_150cm: sensor readings at 150 cm depth All readings are in units degrees Celsius. CAF_BulkDensity.txt: file containing bulk density values ('BulkDensity' in g/cm^3) for 10 cm increments for each of 32 locations at Cook Farm. "Location is indicated in 'Location' field, and sample depths are defined (in cm) by 'Upper_depth' and 'Lower_depth' fields." *** 10 additional locations are currently missing data. These locations will be uploaded when data processing is complete (anticipated in November). *** "CAF_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 2007-2014." This is also part of the attribute table for 'CAF_strips.shp' "CAF_CropCodes.txt: file containing crop code names and crop identities, used in 'CAF_CropID.txt' and 'CAF_strips.shp'" "CAF_ParticleSize.txt: file containing particle size fractions ('Sand', 'Silt', and 'Clay' as percent) for each 'Location' at sensor depths " "('Depth', in cm)." "Spatial data: all spatial data have spatial reference NAD83, UTM11N" "CAF_sensors.shp: file containing locations of each of the 42 monitoring locations, the 'Location' field contains the location name, " which coincides with locations in tabular files. "CAF_strips.shp: file containing areal extents of each sub-field, stip, and crop identities for 2007-2014. Crop identity codes are listed" in 'CAF_CropCodes.txt' CAF_DEM.tif: file containing a 10 x 10 m elevation (in m) grid for Cook Farm. "CAF_Spring_ECa.tif, CAF_Fall_ECa.tif: files containing 10 x 10 m apparent electrical conductivity (mS/m) grids to 1.5 m depth for spring " and fall at Cook Farm.
