Data Products Summary

The principal MODIS data products include the following:

  • Cloud mask at 250 m and 1000 m resolution during the day and 1000 m resolution at night
  • Aerosol concentration and optical properties at 10 km during the day
  • Cloud properties (optical thickness, effective particle radius, thermodynamic phase, cloud top altitude, cloud top temperature, cirrus reflectance) at 1-5 km resolution during the day and 5 km resolution at night
  • Atmospheric temperature and water vapor profiles
  • Vegetation and land-surface cover, conditions, and productivity, defined as:
    • Surface reflectance at 250-m, 500-m, and 1-km resolution
    • Vegetation indices corrected for atmospheric effects, soil, polarization, and directional effects at 250-m and 500-m resolution
