Digital Multi-Day Max/Min/Current Air and Soil
Temperature Protocol

Goals for the Training Session

• Provide an inquiry context for the data
  collection and science content
• Provide accurate science content
• Review procedures for data collection
• Review data entry and analysis
• Discuss classroom implementation ideas
• Collect feedback from participants

3
Inquiry Context

• Which season has the highest temperature? Lowest
  temperature? Why?
• How does the soil temperature range compare with
  the air temperature range?
• What are the latitudes and elevations of other
  GLOBE schools with atmosphere temperature data
  similar to yours?

Why do GLOBE scientists research Max/Min/Current
Air and Soil Temperature?

• To provide a denser network of observations than
  is available using only official weather stations
  for investigating localized variations
• To augment data needed for regional forecasts and
  climate records in areas of the world where there
  are few official weather stations
• To compare with model data, or to use as input to
  run a model

Instruments Digital Multi-day Max / Min
Thermometer

• Two sensors
• One measures air temperature
• One measures soil temperature at a depth of 10cm
• Stores six days of max/min temperatures
• Must be reset to around the time of local solar
  noon one time when it is first set up
• The exact time it is reset is known as the Time
  of Reset

8
The Measurements

• Digital Thermometer Calibration
• Current temperature for air and soil
• Daily maximum and minimum temperatures for air
  and soil

Collecting Data Calibration

• Submerge calibration thermometer in an ice-water
  bath for 10-15 minutes, stir occasionally
• Calibration thermometer should read between -0.5
  C and 0.5 C
• Hang calibration thermometer in instrument
  shelter
• Read five sets of readings
• Record and report data
• to GLOBE Web site

11
Collecting Data Protocol

• For both air and soil temperatures
• Press ON button to read current temperature
• Press the Max/Min button twice to read
  maximum/minimum temperature of first day (D.1)
• Continue to press Max/Min Button once to read
  temperatures of other days (D.2-D.6)
