The keystone instrument on the Earth Observing System (EOS) Terra and Aqua satellites, providing improved understanding of global dynamics.
Raytheon’s MODIS space sensors acquire data that is improving our understanding of global dynamics and processes occurring on the surface of Earth, in the oceans, and in the lower atmosphere.
The measurements provided by MODIS require an extraordinary level of radiometric fidelity and stability over a broad spectral range so that there will be confidence that the properties of the Earth system are being measured, rather than imperfections in the instrument. Accordingly, a key feature that distinguishes MODIS from prior space sensors is the incorporation of extensive onboard calibration sources for comprehensive end-to-end verification of spatial (geometric), spectral, and radiometric calibration
MODIS provides the spectral detail that is vital to understanding the characteristics of, and changes in, land cover, the oceans, and the atmosphere.
