SMOS the global success story continues

ESA's water mission is shedding new light on the meandering Gulf Stream, just one of the SMOS satellite's numerous achievements.
New results unveiled today in Spain show that SMOS is now providing new insights into the movement of the Gulf Stream - one of the most intensely studied current systems.
Originating in the Caribbean and flowing towards the North Atlantic, the current plays an important role in the transfer of heat and salt, influencing the climate of North America's east coast and Europe's west coast.

SMOS has a better look at salinity

Earth observation measurements shouldn't be taken with a pinch of salt. ESA is comparing readings of sea-surface salinity from drifting floats to confirm the SMOS water mission's measurements.
Since its launch in 2009, ESA's Soil Moisture and Ocean Salinity (SMOS) satellite has been helping us to understand the water cycle.

SMOS satellite measurements improve as ground radars switch off

Over a dozen radio signals that have hindered data collection on ESA's SMOS water mission have been switched off. The effort also benefits satellites such as NASA's Aquarius mission, which measures ocean salinity at the same frequency.

ESA's SMOS water mission celebrates first year in orbit

A year ago today, ESA's SMOS satellite was launched to improve our knowledge of the water cycle. We are now not only closer to understanding more about Earth, but the novel technology employed by SMOS is clearly demonstrating a new way of monitoring Earth from space.

SMOS water mission winning battle with interference

The results from ESA's SMOS satellite have been impressive, but the mission has been bugged by patches of interference from radar, TV and radio transmissions in what should be a protected band. Painstaking efforts to reduce these unwanted signals are now paying off.

Europe's Smos mission is slowly but surely meeting the challenge of measuring soil moisture and ocean salinity from space.
The satellite, launched late last year, is attempting to make global maps of these two important parameters using an innovative detection technique.
Its sole instrument, an 8m-wide interferometric radiometer, gives Smos the look of a "space chopper".

ESA's SMOS water mission goes live

ESA's SMOS satellite completed its six-month commissioning this week and formally began operational life. This milestone means the mission is now set to provide much-needed global images of soil moisture and ocean salinity to improve our understanding of the water cycle.
The Soil Moisture and Ocean Salinity (SMOS) satellite was launched on 2 November last year, and has since undergone an intense programme of calibration and commissioning in preparation for its life in service.

Water mission fights interference

Europe's Smos spacecraft is returning valuable new data on the way water is cycled around the globe, despite experiencing continued interference.
The satellite was launched in November to track changes in the wetness of soils and the saltiness of the oceans using a three-armed microwave antenna.
Its detailed maps will soon begin flowing to the scientific community.
But in some parts of the world, Smos is still being blinded by radar networks, and even TV and radio links.

'Tuned' images from water mission

The first fully calibrated images from the European Space Agency's Smos satellite have now been released.
The spacecraft's new pictures show swathes of Scandinavia, Australia and the Amazon.
The maps record the amount of moisture held in soils and of the quantity of salts dissolved in seawater.

In less than four months since launch, the first calibrated images are being delivered by ESA's SMOS mission. These images of 'brightness temperature' translate into clear information on global variations of soil moisture and ocean salinity to advance our understanding of the water cycle
