MODIS (moderate resolution imaging spectroradiometer) has high time resolution, which can support the day visible and day/night infrared spectrum of the Earth's surface every one to two days. MODIS data is very suitable for large-scale Eearth's surface observation and available free of charge. As a result, it has been one of the main detectors of global change research in Earth Observing System (EOS) series satellites.
MODIS data supply much useful information, such as land surface, ocean, phytoplankton...
