  ideas
• Collect feedback from participants
                                           Surface Temperature Protocol



             Inquiry Context
                            • 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?
• How does surface temperature vary with land cover
  (e.g. bare soil, short grass, tall grass, concrete, sand)?

Local Inquiry Example
                               Surface Temperature Protocol

         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

Science Content: What is surface temperature?




     Surface temperature is the radiating
     temperature of the ground surface.
                           Surface Temperature Protocol



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

    Collecting Data: Protocol
• Initially select from Land Cover Sample Sites,
  Atmosphere Study Sites or Soil Moisture Study Sites
• Fill out Supplemental Site Definition Data
• Make Cloud Protocols observations
• Pick nine random observation spots in the study site at
  least 5 m apart
   – Read and record surface temperature
   – Record local time-convert to Universal Time
   – Measure and record snow depth
