Terra | The EOS Flagship
2010年12月18日 · For 20 years, Terra, the flagship Earth observing satellite, has chronicled changes on Earth. Designed and built in the 1980s and 90s, NASA and Lockheed Martin engineers set out to build a satellite that could take simultaneous measurements of Earth’s atmosphere, land, and water. Its mission – to understand how Earth is changing and to ...
About Terra
About Terra. Approximately the size of a small school bus, the Terra satellite carries five instruments that take coincident measurements of the Earth system: Terra is in a circular sun-synchronous polar orbit that takes it from north to south (on the daylight side of …
MODIS - Terra
1 天前 · Moderate Resolution Imaging Spectroradiometer. With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor. For instance, the sensor measures the percent of the planet’s surface ...
Mission - Terra
2 天之前 · In December 1999, NASA launched the Terra satellite as the flagship mission of the Earth Observing System to answer these questions. Terra carries five instruments that observe Earth’s atmosphere, ocean, land, snow and ice, and energy budget. Taken together, these observations provide unique insight into how the Earth system works and how it ...
ASTER | Terra
The Advanced Spaceborne Thermal Emission and Reflection Radiometer obtains high-resolution (15 to 90 square meters per pixel) images of the Earth in 14 different wavelengths of the electromagnetic spectrum, ranging from visible to thermal infrared light. Scientists use ASTER data to create detailed maps of land surface temperature, emissivity ...
Data - Terra
1 天前 · Data. Terra’s five instruments produce 83 core data products which are distributed through the Land Processes Distributed Active Archive Center (LPDAAC), the Atmospheric Science Data Center (ASDC), Ocean Color Web, Level 1 and Atmosphere Archive and Distribution System, and the National Snow and Ice Data Center (NSIDC).

3 天之前 · Terra Instruments. Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget. Each sensor has unique features that enable scientists to meet a wide range of science objectives. The five Terra onboard sensors are: Because all ...
MODIS Data - Terra
4 天之前 · The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.405 and 14.385 µm, and it acquires data at three spatial resolutions — 250m, 500m, and 1,000m.

2 天之前 · As the Flagship Earth Observing Satellite, Terra was the first satellite to look at Earth system science with five sensors dedicated to observing the land, water, and atmosphere. By seeing Earth from the same vantage point, but collecting multiple types of data dedicated to various areas of Earth science, scientists are able to document ...
