Automated Soil and Air Temperature Monitoring Protocol

Abstract:: The purpose of this resource is to continuously measure soil and air temperature at one site. Students install four temperature probes; three are placed in the soil at three different depths and one is placed in an instrument shelter. Students use a data logger to record readings from the probes every 15 minutes. Students transfer the data to their school computers for analysis and submission to the GLOBE database.

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

Abstract:: The purpose of this resource is to record daily measurements of maximum, minimum, and current air and soil temperatures at a common site. One temperature probe is placed inside the instrument shelter while another is installed at a 10 cm depth in the soil. A digital thermometer is used to measure current temperatures as well as daily minimum and maximum temperatures. The daily minimum and maximum temperatures are stored by the instrument for a period of six days and need to be read and recorded within this span of time.

Abstract:: The purpose of this activity is to measure air (and optionally soil) temperature within one hour of solar noon and the maximum and minimum air temperatures for the previous 24 hours. Intended outcomes are that students will learn to read minimum, maximum, and current temperatures using a U-shaped thermometer, understand diurnal and annual temperature variations, and recognize factors that influence atmospheric temperatures. Supporting background materials for both student and teacher are included.
