EOS (Earth Observing System) satellite

In December 1999, the United States National Aeronautics and Space Administration (NASA) successfully launched the Terra satellite, which is a new generation known as the "ball Observing System (EOS)" series of satellites to detect flu in the first operational satellite. The second satellite - Aqua satellite on May 4, 2002 successfully launched, currently operating normally. The third satellites - Aura has been in the July 15, 2004 successfully launched the current test.

MODIS (Moderate-resolution Imaging Spectroradiometer), also known as in-resolution Imaging Spectroradiometer meters, is carrying on the Terra and Aqua satellite on an important sensor. Aqua and Terra's MODIS on the information available will help the global land, sea and air power at a lower level of development and understanding of the process.

MODIS data used by the application of the model can accurately predict changes in global decision-makers and help protect the environment and make important decisions, which may include information on the scope of application of oceanography, atmospheric science and biology and global change.

MODIS sensor has 36-band (frequency spectrum), the space between Resolution 250 meters to 1000 meters, the response period (refer to the satellite observed the same place the shortest intervals) for 1 to 2 days, in such a Under the capacity, MODIS sensor can provide a very dynamic and rich in images of the Earth.

Terra satellite presentation

EOS (Earth Observation System) satellite Earth Observation System of the United States plans a series of satellites in the short title. After a long period of manufacturing and research, the first Earth Observing System (EOS) satellite to orbit the morning of Dec. 18, 1999 launch, the successful launch of the satellite named "TERRA" (Latin translated as "Earth" Mean).

Principal purpose: solar radiation, atmospheric, oceanic and land-based comprehensive observation, access to the sea, land, ice and snow and sun power systems, and other information; land use and land cover long-term study of climate change, natural disaster monitoring and analysis of research and Changes in the atmospheric ozone research; to the realization of the Earth's atmosphere and climate change observation and study of the long-term goals.

Aqua satellite presentation

AQUA satellite launch in the United States in recent years, the second Earth Observation System (EOS) satellite series. AQUA from the Latin, meaning "water." In the next six years, the satellite's six scientific instruments on the Earth's oceans, atmosphere, land, snow cover and vegetation in the region, such as a comprehensive observation, collection of the world's rainfall, water vapor, forming clouds, ocean currents, and other activities of the water cycle data. The use of these data, scientists can conduct further studies on the Earth's water cycle and ecosystem changes in the law, and deepen their understanding of the Earth's ecosystem and environmental changes in the interaction between the understanding.

AQUA satellite can also be temperature and humidity of the atmosphere, sea surface temperature, soil moisture, such as changes in a more precise measurement, the measurement data available for weather forecasting important reference value.
