MODIS (Terra)

MODIS (Terra)
Main objectives	-       Acquire data in 36 spectra bands or groups of wave lengths -       Help our understanding of global dynamics and processes that occurs on the land, in ocean, and lower atmosphere -       Measure visible and infrared radiation and obtaining data that are being used to derive a variety of products

IEEE Transactions on Geoscience and Remote Sensing, 1798-1807. This article shows that the TIR iances from ASTER and MODIS-Terra have met the radio metric calibration accuracy specification and how the Modis Terra MIR channaels have greater bias.
