Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.
Review this page to learn about the background of volcanoes and their eruptions.
Students will describe the changes in a newly-formed volcanic island over the first three years of its life.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.
This mini lesson engages students by watching a NASA video related to seasonal chlorophyll concentration as it relates to net radiation using NASA's Aqua satellite. Students will examine the model and answer the questions.
Students can interact with NASA data to build a custom visualizations of local, regional, or global plant growth patterns over time, using the Earth System Data Explorer to generate plots of satellite data as they develop models of this phenomenon.
