Surface Temperature Protocol: Surface Temperature Protocol


Goals for the Training Session: 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


Inquiry Context: Inquiry Context How does surface temperature vary with land cover (e.g. bare soil, short grass, tall grass, concrete, sand)? How does the time of year affect the surface temperature? How does surface temperature compare with air temperature? Can surface temperature measurements help scientists study the urban heat island effect?


Local Inquiry Example: Local Inquiry Example


Why do GLOBE scientists research surface temperature?: Help calculate the rate of heat and moisture exchange between the atmosphere and the soil Verification of remotely sensed temperature readings Why do GLOBE scientists research surface temperature?


Science Content: What is surface temperature?: Science Content: What is surface temperature? Surface temperature is the radiating temperature of the ground surface.


Instruments: Infrared Thermometer: Instruments: Infrared Thermometer Measures infrared (heat) radiation emanating from surface and converts to temperature Check calibration once a year Use thermal glove
