Abstract:

The remote sensing technique is widely used in Polar Regions, and Moderate Resolution Imaging Spectroradiomete (MODIS) is one of the most important satellite sensors in the domain of remote sensing. In this article, MODIS sensor, including the information of its satellites, its system constitutes, its hardware characteristic, its large spectra and usual applications are briefly introduced first. Then, there is a particular introduction of MODIS's use in Polar Regions, which refers to the polar physiognomy, polar atmosphere and polar ocean, with citing many examples. Atlast, views about the development of MODIS and its series sensors in the future, including the improved applications in Polar Regions are given.

Key words: MODIS, Polar Regions, polar physiognomy, polar atmosphere, polar ocean
