MODIS - Terra
2 days ago · 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 that is covered by clouds almost every day.
Terra | The EOS Flagship
Dec 18, 2010 · 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 ...
Carbon Cycle and Ecosystems - Terra
2 days ago · Carbon is a fundamental part of the Earth system. It is one of the primary building blocks of all organic matter on Earth and a key element in setting Earth’s temperature. Carbon moves from the atmosphere to the land, ocean, and life through biological, chemical, geological and physical processes in a cycle called the carbon cycle.
Water & Energy Cycle | Terra
2 days ago · The movement of water from the ocean to the atmosphere to the land and back to the ocean—the water cycle —is fueled by energy from the Sun. Changes in the energy cycle will ripple into the water cycle. As greenhouses gases retain more energy in the Earth system, the extra energy enhances the water cycle. An enhanced water cycle means more ...

Climate Variability and Change - Terra
4 days ago · Climate Variability and Change. Climate is the sum of weather over time, the average temperatures and rainfall of a place. Earth’s climate—how hot our planet is on average—is set by the Sun. Anything that changes the amount of solar energy that enters the Earth system will change the temperature. By burning fossil fuels, people are ...
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 ...

MODIS Data - Terra
2 days ago · 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.
MODIS Shows Earth is Greener - Terra
It’s called the Moderate Resolution Imaging Spectroradiometer, or MODIS, and its high-resolution data provides very accurate information, helping researchers work out details of what’s happening with Earth’s vegetation, down to the level of 500 meters, or about 1,600 feet, on the ground. The world is a greener place than it was 20 years ...
