Aftermath of a Fall Blizzard

This Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua image, acquired on November 18, 2015 shows the Rocky Mountains following a powerful weather system that dropped more than 0.3 meters (12 inches) of snow along portions of the Front Range. Wind gusts of 112 km/hr (70 mph) and higher were measured during this early-season blizzard.

NASA's Workhorse Instrument

MODIS is a key instrument aboard NASA's Terra (1999 launch) and Aqua (2002 launch) Earth observing satellites. MODIS provides observations for the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands. MODIS and other remote sensing data are improving our understanding of Earth's interrelated systems.


The Earth Observing System Data and Information System is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
