Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017.
We often take the Biosphere, especially its plants and trees, for granted; however, this important sphere also supports almost every aspect of our lives.
Scientists are interested in learning how the vegetation (collection of plants) of an area can be used to study Earth's climate.
This resource helps to identify and access GLOBE protocols and hands-on learning activities that complement the Plant Growth Patterns phenomenon.
Students can interact with NASA data to build a custom visualizations of of local, regional, or global plant growth patterns over time. Use the Earth System Data Explorer to generate plots of satellite data as you develop models of this phenomenon.
See the following datasets in the Earth System Data Explorer:
Students analyze historic plant growth data (i.e., peak bloom dates) of Washington, D.C.’s famous cherry blossom trees, as well as atmospheric near surface temperatures as evidence for explaining the phenomena of earlier peak blooms in our nation’s capital.
Use the Data Literacy Cubes to guide students’ exploration of mapped data of the Earth System to enrich their observations and inferences. This is a flexible resource that may be used with a variety of mapped images. This activity requires a map of Earth data for students to evaluate.
One of the key "vital signs" of Earth's vegetation is the total green leaf area for a given ground area. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra and Aqua satellites collects global Leaf Area Index (LAI) data on a daily basis.
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.
