The MODIS instrument will provide long-term observations from which an enhanced knowledge of global dynamics and processes occurring on the surface of the Earth and in the lower atmosphere can be derived. This multidisciplinary instrument yields simultaneous, congruent observations of high-priority atmospheric (aerosol and cloud properties, water vapor, and temperature profiles), oceanic (sea-surface temperature and chlorophyll), and land-surface features (land cover changes, land-surface temperature, and vegetation properties). The instrument is expected to make major contributions to understanding the global Earth system, including interactions among land, ocean, and atmospheric processes.

This is sample data for one day, August 30, 2000. The MODIS data subset covers all or part of the geographical areas of the states of Washington, Oregon, Idaho, Montana, and Nevada in the continental United States (CONUS) and adjacent parts of Canada.

The data sample includes clear sky, clouds, and wildfire smoke and haze. The MODIS subset covers more ground area than the subsets for ASTER and MISR. The MODIS subset covers less territory on the ground than does the subset for CERES.

Note that scan lines exhibit the "bow-tie" effect for samples along scan far from nadir.
