Earth has a limited amount of water that recycles itself in what is called the "Ëœwater cycle'. Climate change, weather and human life are highly affected by changes in this continuous, interconnected cycle. Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, forecasting our weather, predicting floods and droughts, and improving water management for human use. Recent advances in Earth observation (EO)...

NASA mission managers are assessing options for future operations of the venerable QuikScat satellite following the age-related failure of a mechanism that spins the scatterometer antenna. This spinning antenna had been providing near-real-time ocean- surface wind speed and direction data over 90 percent of the global ocean every day. In recent months, the QuikScat project team has been monitoring a pattern of increasing friction in the bearings that allow the antenna to spin, leading to...

A small NASA aircraft completed its first successful science flight Thursday as part of an expedition to study the receding Arctic sea ice and improve understanding of its life cycle and the long-term stability of the Arctic ice cover. The mission continues through July 24. NASA's Characterization of Arctic Sea Ice Experiment, known as CASIE, began a series of unmanned aircraft system flights in coordination with satellites. Working with the University of Colorado and its research partners,...

BOULDER, Colo., June 16 /PRNewswire-FirstCall/ -- This month marks a decade of success for NASA's QuikSCAT mission, one that continues to provide a wealth of information about Earth's climate since its launch June 19, 1999. Although QuikSCAT's mission life was designed for two years, the spacecraft continues to operate into its tenth year and its groundbreaking research is being used to help predict severe weather patterns, create wave-prediction models and to observe global climate change....

An Earth-observing satellite that has provided early detection of ocean storms and advanced the scientific exploration of global ocean wind patterns has been recognized for helping scientists better understand our home planet. NASA and the U.S. Department of the Interior Tuesday presented William T. Pecora Awards to NASA's Quick Scatterometer, or QuikSCAT, mission team and Samuel N. Goward of the University of Maryland, College Park. The two agencies present individual and group Pecora Awards...

An ESA campaign carried out in Austria has demonstrated how snow, a key component in the Earth's water cycle and important source of fresh water, can be measured from space using radar. The campaign supports one of the main objectives of the candidate Earth Explorer CoReH2O. Cold Regions Hydrology High-Resolution Observatory (CoReH2O) is one of six candidate Earth Explorer missions that has just completed an assessment study and will be presented to the science community at a User...

By Tad Walch Deseret News PROVO -- Forecasters trying to predict the bruising path of Hurricane Ike used data developed and supported by a team at Brigham Young University. Engineering professor David Long helped write computer code for a satellite sensor that provides important information about the wind speed and wind direction of ocean storms. The sensor, known as SeaWinds, was launched aboard the QuikSCAT satellite in 1999. The sensor produces images processed by Long and two...

PASADENA, Calif. - A new NASA-led study found a 23-percent loss in the extent of the Arctic's thick, year-round sea ice cover during the past two winters. This drastic reduction of perennial winter sea ice is the primary cause of this summer's fastest-ever sea ice retreat on record and subsequent smallest-ever extent of total Arctic coverage. A team led by Son Nghiem of NASA's Jet Propulsion Laboratory, Pasadena, Calif., studied trends in Arctic perennial ice cover by combining data from...

For the first time, NASA scientists using space-based measurements have directly monitored and measured the complete cycle of water movement for an entire continent. Using satellite data from three Earth-orbiting NASA missions -- Quick Scatterometer (QuikScat), Gravity Recovery and Climate Experiment (Grace), and Tropical Rainfall Measuring Mission (TRMM) -- a science team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., directly observed the seasonal cycling of water into and out of...

ESA -- Heavy rainfall and flooding from Typhoon Matsa killed at least 12 people and caused millions of euros worth of damage in China. In Matsa's aftermath, unique data from ESA's ERS-2 spacecraft reveal the interior wind fields powering it at its height. China's ninth typhoon this year, Matsa first came ashore at Yuhan County in Zhejiang Province on 6 August, with reported winds up to 250 kilometres per hour. Matsa brought heavy rains and serious damage to several coastal provinces and...
