The objective of monitoring soil temperature is to document soil freeze-thaw dates associated with seasonal transitions, to estimate the timing of snowpack development and snowmelt, and to provide a basis for comparison among sites of different elevation and soil type. Information collected through this methodology is a time-series dataset containing date, time and soil temperature (\u00b0C) data. A subset of this information collected through this methodology is a time-series dataset containing date, time air temperature (\u00b0C), and relative humidity data.\n\nI've provided an example data file name, KATM_2009_01_S999_20130702_20140801_ST_10366443.csv. Data files contained on this reference are named used the following convention:  \n1. park_code (KATM or LACL) (from tbl_plot on SWAN_Vegetation database)\n2. Three part convention that identifies each unique veg site location. In this example, \"2007\" corresponds to grts_year, \"02\" to the elevation_band_code and \"006\" to the grts_num (from tbl_plot on SWAN_Vegetation database)\n3. Date range in selected file where data is actually present. In this example, the first row of data is from 6/28/2011 and the last row of data is from 7/3/2012. \n4. Two letter code for what type of data is held on file, \"ST\" for soil temp only, \"RH\" for when relative humidity data is present\n5. sensor_serial_num, IE: assigned HOBO number (from tbl_plot_sample_soil_sensor on SWAN_Vegetation database)\n\nData files contained on this reference were loaded into the SWAN_Vegetation database using a script.
