Paper Abstract

MODIS, a 36 band (0.42 - 14.24 micrometer) moderate resolution imaging spectroradiometer is the keystone sensor for the 15 year (1998-2013) Earth Observing System (EOS). MODIS sensors on both the AM and PM EOS spacecraft will each collect data from the entire globe every two days. This data will be used to generate numerous scientific products which will enhance knowledge of changes in the global climate system due to both natural and anthropogenic causes.

MODIS, under development by the Santa Barbara Research Center (SBRC), Goleta, California, and the EOS Project at the Goddard Space Flight Center (GSFC), Greenbelt, Maryland, will include bands with spatial resolutions of 250, 500 or 1,000 meters at nadir, SNR’s as large as several thousand, onboard spatial, spectral and radiometric calibration, solar and lunar radiometric stability monitoring, knowledge of pixel location to less than 500 meters (including spacecraft errors) and radiometric accuracy of 5 percent or less for the 19 reflected solar bands and 1 percent or less for the 17 thermal emission bands. Polarization sensitivity will be limited to less than two percent for bands with wavelengths less than 2.2 micrometers.
