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.

Dr. Norman Loeb, an atmospheric scientist at NASA’s Langley Research Center in Hampton, Virginia, is the principal investigator for an experiment called the Clouds and the Earth’s Radiant Energy System (CERES). CERES instruments measure how much of the sun’s energy is reflected back to space and how much thermal energy is emitted by Earth to space.

My NASA Data has recently released several new resources, StoryMaps, for use in educational settings.

This resource helps to identify and access GLOBE protocols and hands-on learning activities that complement the Air Quality phenomenon.

Explore and connect to the GLOBE Urban protocol bundle.
