Southwest Alaska Network Ground Based Vegetation Monitoring: Soil Temperature Logger Files 2007-2023

Temperature sensors are installed at a subset of readily accessible, permanent plots to monitor soil temperature. 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 (°C) data. A subset of this information collected through this methodology is a time-series dataset containing date, time air temperature (°C), and relative humidity data. I'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: 1. park_code (KATM or LACL) (from tbl_plot on SWAN_Vegetation database) 2. 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) 3. 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. 4. 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 5. sensor_serial_num, IE: assigned HOBO number (from tbl_plot_sample_soil_sensor on SWAN_Vegetation database) Data files contained on this reference were loaded into the SWAN_Vegetation database using a script. Data files contained on this reference can also be accessed on the SWAN_Veg_SoilSensorObservation tables found on the Southwest Alaska Network Ground Based Vegetation Monitoring 2007-2024 Survey Tabular Datasets reference (https://irma.nps.gov/DataStore/Reference/Profile/2315057).
