Aura
PDF icon Aura_Brochure.pdf

Aura’s four instruments study the atmosphere’s chemistry and dynamics, and enable us to investigate questions about ozone trends, air quality changes and their linkage to climate change. Aura’s measurements provide accurate data for predictive models and useful information for local and national agency decision support systems. Aura was the third in a series of large Earth observing platforms to be flown by the National Aeronautics and Space Administration (NASA) with international contributions. Aura along with EOS Terra (launched December, 1999) and Aqua (launched May, 2002) provide an unprecedented view of the global Earth system.

Aqua
PDF icon Aqua_brochure.pdf

Aqua is a satellite mission aimed at improving our understanding of the Earth/atmosphere system, along with changes occurring within it, through the monitoring and analysis of dozens of Earth variables from a space-based platform orbiting the Earth. Aqua is part of the Earth Observing System (EOS), an international Earth-focused satellite program centered at the United States (U.S.) National Aeronautics and Space Administration (NASA).

Gravity Recovery And Climate Experiment (GRACE)
PDF icon GRACE.pdf

While gravity is much weaker than other basic forces in nature, such as magnetism and electricity, its effects are ubiquitous and dramatic. Gravity controls everything from the motion of the ocean tides to the expansion of the entire Universe. To learn more about the mysteries of gravity, twin satellites named GRACE, short for the Gravity Recovery and Climate Experiment, are being used to make detailed measurements of Earth’s gravity field.

ICESat
PDF icon ICESat_Brochure.pdf

The primary goal of ICESat is to quantify ice sheet mass balance and understand how changes in the Earth’s atmosphere and climate affect the polar ice masses and global sea level. ICESat also measures global distributions of clouds and aerosols for studies of their effects on atmospheric processes and global change, as well as land topography, sea ice, and vegetation cover.

Moderate-Resolution Imaging Spectroradiometer (MODIS)
PDF icon MODIS.pdf

The first EOS satellite, called Terra, was launched on December 18, 1999, carrying five remote sensors. The most comprehensive EOS sensor is MODIS, the Moderate Resolution Imaging Spectroradiometer. MODIS offers a unique combination of features: it detects a wide spectral range of electromagnetic energy; it takes measurements at three spatial resolutions (levels of detail); it takes measurements all day, every day; and it has a wide field of view.

AIRS/AMSU/HSB
PDF icon 2001AIRS.pdf

The Atmospheric Infrared Sounder (AIRS), together with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB) (Note: The HSB instrument failed after reaching orbit.) on the Aqua mission, represents the most advanced sounding system ever deployed in space. The system is capable of measuring the atmospheric temperature in the troposphere with radiosonde accuracies of 1 K over 1 km-thick layers under both clear and cloudy conditions, while the accuracy of the derived moisture profiles exceed that obtained by radiosondes.

Advanced Microwave Scanning Radiometer for EOS (AMSR-E)
PDF icon amsr-e.pdf

How clouds, water vapor, precipitation, sea ice, soil moisture, and snow cover respond to increasing atmospheric levels of greenhouse gases is still unclear, and they all have the potential to either enhance or suppress global warming. The same can be said for their influence on natural climate fluctuations. The data that AMSR-E provides is being utilized by climate researchers to develop a better understanding of climate change.

Clouds and the Earth's Radiant Energy System (CERES)
PDF icon CERES_brochure.pdf

NASA’s Earth Observing System (EOS) is part of an international program for studying the Earth from space using a multiple-instrument, multiple-satellite approach. This EOS program is critical for improving our scientific understanding of ongoing natural and human-induced global climate change and providing a sound scientific basis for developing global environmental policies.

Measurements Of Pollution In The Troposphere (MOPITT )
PDF icon MOPITT broch.pdf

Life on Earth depends on the atmosphere. It provides oxygen for respiration, transports gases around the globe and protects life from harmful ultraviolet radiation. With a human population of over 6 billion, the quality of this life-sustaining envelope is vital to our continued survival. The Canadian Space Agency’s Measurements Of Pollution In The Troposphere ( MOPITT ) instrument is designed to monitor from space the health of this thin layer of atmosphere, and give an early warning of unexpected changes.
