Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Past Methods (No longer in use)

  • Plot establishment
    Started: 1993-01-13
    Ended: 2013-12-31

    Two sets of paired plots were established, each pair consisting of a plot where snow was removed after each snowfall, and a plot where snow cover was left in place

  • Soil temperature measurements
    Started: 1993-01-13
    Ended: 2013-12-31

    Soil temperature measured continuously at 4 depths: 2 cm above; 5, 15 and 30 cm below soil surface.

    Instrumentation: 4-point thermocouples

  • Temperature
    Started: 1993-01-13
    Ended: 2013-12-31

    15-minute averages of temperature captured by two datalogger schemes

    Instrumentation: Campbell Scientific 21X datalogger; Analog-digital converter

    Software: Turbo Pascal
