MODIS is ideal for monitoring large-scale changes in the biosphere that are yielding new insights into the workings of the global carbon cycle. MODIS helps scientists determine the amount of water vapor in a column of the atmosphere and the vertical distribution of temperature and water vapor-measurements crucial to understanding Earth’s climate system. Aerosols enter the atmosphere from manmade sources like pollution and biomass burning and natural sources like dust storms, volcanic eruptions, and forest fires.
MODIS also measures the properties of aerosols-tiny liquid or solid particles in the atmosphere. In addition to recording the frequency and distribution of cloud cover, MODIS measures the properties of clouds such as the distribution and size of cloud droplets in both liquid water and ice clouds. This wide spatial coverage enables MODIS, together with MISR and CERES, to help scientists determine the impact of clouds and aerosols on the Earth’s energy budget. For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor.

When conditions do not permit reliable oil delineation (e.g., clouds, lack of sun glint), synthetic aperture radar (SAR) oil delineation is obtained from These images were processed at the University of South Florida, College of Marine Science and made available in near real-time. Depending on the solar and satellite viewing geometry as well as other factors, oil slicks can appear darker or brighter than the surrounding water, and they can have different spectral shapes than other ocean features. Recent article by Hu et al.(2009), and another example for a turbid estuary can be found in The principles to use MODIS imagery for oil spill detection are summarized in a

The prediction of the oil movement with water circulation is being performed by the Oil entrained in the Loop Current will be transported to the Florida Straits and the east coast of the U.S. MERIS satellite RGB images to show the location and size of the subsequent oil spill on the ocean surface, and provides 1-km resolution MODIS Sea Surface Temperature imagery to examine the position of the oil spill relative toe major ocean circulation features such as the
