Soil moisture and ocean salinity satellite ready for launch
October 30, 2009A new European Earth observation satellite will be launched in the early hours of Monday morning (2 November 2009) from the Plesetsk Cosmodrome in northern Russia.
The European Space Agency (ESA) Soil Moisture & Ocean Salinity (SMOS - pronounced SMOSS) satellite aims to measure both moisture levels in the Earth's soils and the saltiness (salinity) of the surface waters of the world's oceans from space for the very first time. British scientists and engineers have been involved in the mission from the start.
Global measurements of salinity and soil moisture will improve our understanding of how water is transported around the Earth, and how it circulates around the oceans, and lead to more accurate weather forecasts and climate simulations.
Professor Meric Srokosz from the National Oceanography Centre in Southampton, who was part of the international team that first proposed the mission in 1998, said, "The temperature and salinity of the water in the oceans determine its density, variations in which are important in driving ocean currents. We've been making salinity measurements from ships for many years, but with SMOS we will be able to get a global picture every few days."
"The oceans play a major role in the climate system and possible future changes in currents are important as the oceans interact with the atmosphere, taking up, releasing and re-distributing heat and freshwater. These interactions are key processes affecting both weather and climate," he added.
Professor Robert Gurney from the University of Reading and the National Centre for Earth Observation, who is working on the mission, said, "SMOS will give us global measurements of soil moisture for the very first time. The mission itself is very challenging because it is the first of its type, and allows us to look at a key area of the planet's water cycle. Soil moisture is important for understanding and predicting floods and droughts, and for predicting the future climate."
Dr Phil Newton, NERC's Director of Science Delivery, said, "The great advances in understanding weather, climate and environmental change promised by a successful SMOS mission cannot be achieved by single European nations acting alone. The European Space Agency provides an essential framework for pooling our intellectual, technological and financial resources, so making possible this sort of big science."
The launch of SMOS comes during the build-up to the crucial climate change talks in Copenhagen in December. Director General of the British National Space Centre (BNSC) Dr David Williams said, "SMOS is an important mission with key UK involvement. Satellites such as SMOS are vital for predictions of how our climate is changing and British scientists and engineers are world leaders in using data from space to improve our understanding of the Earth. The recently-opened ESA research facility at Harwell in Oxfordshire will reinforce the UK's focus on climate change research."
SMOS is the second of ESA's Earth Explorer missions and follows the successful launch of the GOCE (Gravity field and steady state Ocean Circulation Explorer) satellite earlier this year.

As preparations for the launch of SMOS and Proba-2 continue on schedule, the engineers and technicians at the Russian launch site say goodbye as both satellites are encapsulated within the half-shells of the Rockot fairing.
Satellites unlock secret to northern India's vanishing water
Using NASA satellite data, scientists have found that groundwater levels in northern India have been declining by as much as one foot per year over the past decade. Researchers concluded the loss is almost entirely due to human activity.
Dry autumns and winters may lead to fewer tornadoes in the spring, says UGA researcher
Global warming will likely mean more unpredictable weather, scientists say, and a new study by researchers at the University of Georgia pins down, possibly for the first time, how drought conditions in an area's fall and winter may effect tornado activity the following spring.
Rainforest rehab in every sense
Sophisticated sensors that measure leaf wetness, soil moisture and temperature are helping rehabilitate rainforest in the Springbrook World Heritage precinct in south-east Queensland.
NASA uses satellite to unearth innovation in crop forecasting
Soil moisture is essential for seeds to germinate and for crops to grow. But record droughts and scorching temperatures in certain parts of the globe in recent years have caused soil to dry up, crippling crop production.
Drought, urbanization were ingredients for Atlanta's perfect storm
On March 14, 2008, a tornado swept through downtown Atlanta, its 130 mile-per-hour winds ripping holes in the roof of the Georgia Dome, blowing out office windows, and trashing parts of Centennial Olympic Park.

Orchard floor and groundcover management is important to fruit growers, affecting the efficiency of orchard operations, fruit tree performance, and soil quality.
Protecting wine grapes from heat and drought
Deficit irrigation is an agricultural technique used to achieve a variety of results depending on the crop. For white wine grapes, it balances the crop load by limiting the canopy size so there aren't too many leaves shading the grapes.
