NASA has selected an ocean wind study proposal led by the University of Michigan from among 19 submitted to the agency's Announcement of Opportunity for small spaceflight investigations of the Earth system. The proposed mission will make accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes, which could help lead to better weather forecasting. The competitively-selected proposal, the Cyclone Global Navigation Satellite System (CYGNSS), is...

Students Help NASA Validate Satellites With Cloud Observations

In between recess, geography class and eating the lunch their moms packed, NASA scientists have found the time to help validate Earth-observing satellites. These scientists are the younger variety -- students in NASA's S'COOL project (Students' Cloud Observations On-Line), a worldwide effort to collect cloud observations from the ground. The students make observations like a NASA scientist and submit reports for their area to NASA. In return, the students receive a corresponding cloud...

HAMPTON, Va., June 9, 2011 /PRNewswire-USNewswire/ -- For a satellite that's only five years old, CALIPSO has accomplished a lot. The Earth-observing spacecraft took its three-billionth photo - actually a "lidar profile" - on June 2. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) June 7 marked the fifth year in space for the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation satellite. For images go to...

Mention the "A-Train" and most people probably think of the jazz legend Billy Strayhorn or perhaps New York City subway trains "” not climate change. However, it turns out that a convoy of "A-Train" satellites has emerged as one of the most powerful tools scientists have for understanding our planet's changing climate. The formation of satellites "” which currently includes Aqua, CloudSat, Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) and Aura...

Three NASA satellites are keeping tabs on Typhoon Megi and noticed that it was strengthening in the South China Sea today, but increasing wind shear may again weaken the system over the next couple of days. NASA's TRMM, CloudSat and Aqua satellite captured images of Megi's clouds, rainfall and eye as they passed over the storm and saw clouds higher than 9 miles filled with ice, creating heavy rainfall. The Tropical Rainfall Measuring Mission (TRMM) satellite passed over Typhoon Megi from its...

Towering thunderstorms and heavy rainfall are two things that NASA's CloudSat satellite saw as it passed over Typhoon Malakas, and those two factors confirm a strong storm. NASA's CloudSat satellite's Cloud Profiling Radar can basically slice a tropical cyclone in half and take a look at its clouds and rainfall, and that's what it did when it passed over Typhoon Malakas on Sept. 23. CloudSat flew over Typhoon Malakas during the daytime on Sept. 23. At that time, Malakas had a minimum central...

NASA's CloudSat satellite captured a profile of Hurricane Karl as it began making landfall in Mexico today. The satellite data revealed very high, icy cloud tops in Karl's powerful thunderstorms, and moderate to heavy rainfall from the storm. Meanwhile, NASA's "GRIP" mission was also underway as aircraft were gathering valuable data about Hurricane Karl as he moves inland. NASA's Genesis and Rapid Intensification Processes mission (known as GRIP) is still underway and is studying the rapid...

The air we breathe doesn't always come from our own backyard. In fact, sometimes it doesn't even come from our neighbors. On April 22, 2010, a NASA satellite captured the appearance of a large dust cloud over the eastern coast of United States that originated on the other side of the world -- in China. "Dust can stimulate the production of more clouds, altering local weather and potentially the climate," said Zhoayan Liu, a researcher at the National Institute of Aerospace and NASA's Langley...

After nearly 5 years of concurrent operations with the Afternoon Constellation, known as the "A-Train," the PARASOL satellite is going on another orbit "track." The A-Train includes a number of NASA satellites that orbit the Earth one behind the other on the same track and until this month, PARASOL has been part of that train. PARASOL is an Earth observation mission, managed by the French Space Agency (CNES). PARASOL stands for "Polarization and Anisotropy of Reflectances for Atmospheric...
