Rosalie Murphy, JPL Earth Science and Technology Directorate The ocean covers 71 percent of Earth's surface and affects weather over the entire globe. Hurricanes and storms that begin far out over the ocean affect people on land and interfere with shipping at sea. And the ocean stores carbon and heat, which are transported from the ocean to the air and back, allowing for photosynthesis and affecting Earth's climate. To understand all these processes, scientists need information about winds...

Hidden Cycles Of Sea Winds To Be Revealed By NASA's RapidScat
2014-07-08 03:19:00

NASA's Jet Propulsion Laboratory Ocean waves, the hot sun, sea breezes -- the right combination makes a great day at the beach. A different combination makes a killer hurricane. The complex interactions of the ocean and the air above it that can create such different outcomes are not yet fully known. Scientists would especially like to understand the role that the daily heat of the sun plays in creating winds. In a few months, NASA will send an ocean wind-monitoring instrument to a...

QuikScat's Eye On Ocean Winds Lives On After 15 Years
2014-06-20 03:55:48

Rosalie Murphy, NASA's Jet Propulsion Laboratory Today (June 19) marks the 15th anniversary of the launch of NASA's QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners. On this anniversary, the mission's team is preparing...

WASHINGTON, May 15, 2014 /PRNewswire-USNewswire/ -- A new NASA Earth-observing mission that will measure ocean winds from the International Space Station has arrived at NASA's Kennedy Space Center in Florida to begin final preparations for launch. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The International Space Station (ISS)-RapidScat scatterometer instrument arrived May 12 after a cross-country trip from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. The...

NASA ISS-RapidScat Built On The Fly
2013-10-30 11:52:06

Brett Smith for redOrbit.com - Your Universe Online The best chefs in the world can create a gourmet dish from leftover ingredients and NASA scientists have set out to show they can accomplish a similar feat though the ISS-RapidScat science mission. An abbreviated form of Rapid Scatterometer, ISS-RapidScat was fashioned from spare parts and put together on a relatively short time scale. The mission will monitor ocean winds from the International Space Station. Scientists study ocean...

Seasat Blazed The Trail For Many Mission
2013-06-28 05:27:14

April Flowers for redOrbit.com - Your Universe Online Even if they don't last long, history tends to look fondly upon trailblazers. Thirty-five years ago this week, NASA's Jet Propulsion Laboratory (JPL) launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure. Seasat is still in orbit, however, shining in the night sky at magnitude...

Ocean Winds To Be Monitored From The International Space Station
2013-01-30 07:48:19

April Flowers for redOrbit.com - Your Universe Online NASA will launch the ISS-RapidScat instrument to the International Space Station (ISS) in 2014. Reusing hardware built to test parts of the QuikScat satellite, the new instrument will measure ocean-surface wind speed and direction. ISS-RapidScat will help improve weather forecasts here on Earth, including hurricane monitoring, and will further scientific understanding of how ocean-atmosphere interactions influence Earth's climate....

Amazon Rainforest Under Threat From Climate Change
2013-01-18 06:36:22

April Flowers for redOrbit.com - Your Universe Online A megadrought that started in 2005 is still affecting a portion of the Amazon Rainforest twice the size of California, a new study led by NASA's Jet Propulsion Laboratory (JPL) finds. The results of this study, combined with the observed recurrences of droughts every few years and associated damage to forests in both the southern and western Amazon over the past decade, reveal that the rainforest might be showing the initial signs of...

Over 30 Years Of Global Soil Moisture Observations For Climate Applications
2012-06-20 04:14:52

[ Watch the Video ] Water held in soil plays an important role in the climate system. The dataset released by ESA is the first remote-sensing soil moisture data record spanning the period 1978 to 2010 — a predecessor of the data now being provided by ESA´s SMOS mission. The datasets are now available to the science community for feedback analyses and climate model validation. The amount of water held in global soils makes up only about 0.001% of the total water found on...

Written by Rosemary Sullivant, NASA/JPL The breakthrough moment for oceanographer Gary Lagerloef, the principal investigator for NASA's new Aquarius mission, came in 1991. That's when he knew it would be possible to make precise measurements of ocean salinity from space. It has taken nearly two decades to turn that possibility into a reality. Lagerloef was looking at data collected by a NASA aircraft flying over the ocean off the coast of Maryland. It was testing a new radiometer, an...
