Investigation 2: Sensing volcanic effects from space

This investigation supplements traditional curriculum materials about volcanoes by focusing on how the effects of volcanic activity can be remotely sensed and monitored. Students observe different types of data gathered by NASA to monitor Mount Spurr in Alaska. By comparing visual data captured in a photograph taken from the Space Shuttle to the remotely sensed signals of the TOMS (Total Ozone Mapping Spectrometer) and AVHRR (Advanced Very High Resolution Radiometer), students begin to see relationships between volcanic eruptions and the global environment. Specifically, students use the data to determine if a correlation exists between aerosols and atmospheric temperature. The investigation reinforces graphic skills and evaluation skills. 5-8 Module 1 Investigation 2 in .pdf format Investigation 2 Student Materials in .pdf format
