These satellite images are from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on two satellites, Aqua and Terra. MODIS captures 36 electromagnetic wavelength bands to measure atmospheric water vapor, ozone, aerosols, land fire, surface temperature, and many other important variables of global climate. These images are visible light and clearly show the change in deciduous canopy cover within roughly a month of time. Spatial resolutions are between 250 m to 1 km.
