Terra | The EOS Flagship Terra: The EOS Flagship Terra explores the connections between Earth’s atmosphere, land, snow and ice, ocean, and energy balance to understand Earth’s climate and to map the impact of human activity and natural disasters on communities and ecosystems
MODIS | Terra Terra Operational Changes and Data Updates Over the past three years, the Terra mission has performed multiple maneuvers that have led to changes in the satellite’s consistent 20+ year orbit* Today, Terra continues slowly drifting to an increasingly earlier overpass time and lower altitude While the orbital changes have had little to no impact on instrument data collection or quality, data
Mission - Terra Terra observations reveal humanity’s impact on the planet and provide crucial data about natural hazards like fire and volcanoes See Terra science Terra is an international mission carrying instruments from the United States, Japan, and Canada
MOPITT | Terra Terra, which carries five instruments, launched in December 1999 on a six-year mission designed to study the planet’s land, ocean, atmosphere and biosphere simultaneously as the flagship mission of NASA’s Earth Observing system Terra is a partnership between the United States, Canada and Japan
ASTER | Terra The Terra Project fully expects the Terra platform and all five instruments to operate past 2026 allowing them to maintain their status as leaders in Earth science data production Terra’s long-term data record will continue to contribute to the Earth Science Division’s key science questions: How is the global Earth system changing?
Multimedia - Terra 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 relationships between Earth’s systems and examine their
MODIS - Terra 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
ASTER | Terra This perspective image of a complex volcanic landscape in the Andean mountain range was assembled from data acquired by ASTER on April 9, 2003 ASTER produces images using infrared, red, and green wavelengths of light Vegetated areas range in color from red to pink, snow is white, water is black, and bare rock is earth-toned The Advanced Spaceborne Thermal Emission and Reflection Radiometer
Satellite Observations - Terra Part II Track Pollution from Space To improve air quality, it is important to know what contributes to polluting the air Haze comes from a variety of sources Your skies may be hazy from local traffic, or industry such as for example coal burning power plants, or the pollution may be coming in from somewhere else farther away Satellite images help identify large areas of pollution caused by
Data - Terra 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) Each data set is specialized and many work in concert with other data products
