MODIS - Terra
1 day 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
1 day 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
1 day 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 ...

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 ...
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 ...
Earth’s Surface & Interior | Terra
2 days ago · The Earth’s surface plays a critical role in the Earth system by interacting with the ocean and the atmosphere. To understand the Earth system, scientists must observe how the Earth’s surface changes as a result of interactions between the atmosphere and ocean (coastal erosion, landslides) and how tectonics and volcanism impact the atmosphere and ocean.
Climate Variability and Change - Terra
1 day 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 ...
MISR - Terra
3 days ago · MISR is a new type of instrument designed to address this need — it views the Earth with cameras pointed at nine different angles. One camera points toward nadir, and the others provide forward and aftward view angles, at the Earth’s surface, of 26.1°, 45.6°, 60.0°, and 70.5°. As the instrument flies overhead, each region of the Earth ...
