The new Cloud-Aerosol Transport System (CATS) is a technology demonstration mission using three-wavelength lasers to extend satellite observations of small particles in the atmosphere from volcanoes, air pollution, dust, and smoke. These aerosol particles pose human health risks at ground level and influence global climate through their impact on cloud cover and solar radiation in Earth's atmosphere. CATS is scheduled to launch Sept. 12 on another SpaceX ISS commercial resupply flight from Cape Canaveral Air Force Station.
"With these two instruments launching to the space station, ISS will come into its own as an important platform for studying the Earth system and global change," said Julie Robinson, space station chief scientist at NASA's Johnson Space Center in Houston. "This is just the beginning of the space station becoming a part of the global Earth-observing network."
NASA also uses a wide array of research aircraft equipped with sophisticated sensors to advance Earth science research. This year, NASA is sponsoring 12 flight campaigns that will study the polar ice sheets, urban air pollution, hurricanes, ecosystem health and more over the United States, Central and South America, Antarctica, and the Arctic Circle.
Putting satellite data to work meeting local and regional needs around the world is another part of NASA's Earth science mission. In 2014, projects sponsored by the NASA Applied Sciences Program will tackle ecosystem issues in the Gulf of Mexico, water scarcity in the U.S. Southwest, and flood management in the Mekong River delta.
NASA continues to push the boundaries of current technologies to find new ways to see our complex planet in more detail and with greater accuracy. This year, NASA's Earth Science Technology Office will test new sensors to improve measurements of water levels in lakes and reservoirs, carbon dioxide, terrestrial ecosystems, and natural hazards such as earthquakes and tsunamis.
NASA monitors Earth's vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns. NASA develops new ways to observe and study Earth's interconnected natural systems with long-term data records and computer analysis tools to better see how our planet is changing. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.
