Research and Application News
In 2013, the vast majority of worldwide climate indicators-greenhouse gases, sea levels, global temperatures, etc.-continued to reflect trends of a warmer planet, according to the indicators assessed in the State of the Climate in 2013 report, released online on 17 July 2014 by the American Meteorological Society.
Satellites provide a unique perspective for monitoring natural hazards, providing both global and regional information to support analysis and forecasts as well as decision-making activities of emergency management personnel. Geosynchronous sensors can provide continuous regional information on a continental scale in near real time, as frequently seen in weather monitoring by National Oceanic and Atmospheric Administration (NOAA) operational satellites.
Atmospheric gravity waves influence the weather and long-term, climate-related atmospheric processes. For a number of nights between 29 June and 23 July 2014, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Falcon research aircraft will be flying over the New Zealand Alps (Southern Alps) to investigate how these waves propagate from Earth's surface up to an altitude of around 100 kilometres using modern laser metrology and other instruments. The results will help to improve climate and weather prediction models.

Monitoring wildlife in the Arctic is difficult. Study areas are cold, barren and often inaccessible. For decades scientists have struggled to study animals, like polar bears, which live in these remote areas. Now researchers at the U.S. Geological Survey have begun testing a new, yet counterintuitive solution - rather then get close to the animals, monitor them from afar.

Scientists working with data from NASA's Aquarius instrument have released worldwide maps of soil moisture, showing how the wetness of the land fluctuates with the seasons and weather phenomena.

Researchers have figured out a new way to predict which rivers are most at risk of dangerous flooding.

Some things go swimmingly with a summer trip to the beach - sunscreen, mystery novels, cold beverages and sandcastles. Other things - like aquatic algae - are best avoided. The Landsat 8 satellite is helping researchers spot these organisms from space, gathering information that could direct beachgoers away from contaminated bays and beaches.
Knowing where water vapour is in the atmosphere is one of many factors forecasters use to identify weather features. The NASA/NOAA GOES Project has now created two new types of animations based on satellite data that indicate where water vapour is moving over the Atlantic and Eastern Pacific oceans.
Glacial retreat on the West Antarctic Ice Sheet has been a matter of scientific interest for decades and holds serious implications for sea level rise, but difficulties involved in conducting research in this inaccessible location limited early investigation. As remote sensing improved, so too did the capacity to observe glacial patterns on the Antarctic continent.

Subsidence, rockfalls and landslides threaten potentially devastating human and economic consequences across Europe - but satellites can help.
A NASA high-altitude ER-2 aircraft concluded its participation 16 June in a study aimed at gaining a better understanding of precipitation over mountainous terrain.
Hurricane Cristina intensified rapidly on 12 June and infrared satellite data showed cloud top temperatures became extremely cold as thunderstorms towered to the top of the troposphere. One day later, Cristina was weakening quickly and infrared data showed cloud top temperatures were warming as the cloud tops dropped.

Every spring, as the weather warms, trees in forests up and down the east coast explode in a bright green display of life as leaves fill their branches, and every fall, those same leaves provide one of nature's great colour displays of vivid yellow, orange and red.

Calling all app developers: register today for the opportunity to spend a week at ESA developing news ideas and concepts for mobile apps using satellite Earth observation data.

Data from the Meteosat satellite has been used to measure the temperature of lava at a remote volcano in Africa.

Information from Earth-observing satellites is being used to protect and sustainably manage our natural resources.

During this year's Atlantic hurricane season, NASA is redoubling its efforts to probe the inner workings of hurricanes and tropical storms with two unmanned Global Hawk aircraft flying over storms and two new space-based missions.

Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina.
A new illustration of the seafloor, created by two of the world's leading ocean floor mapping experts that details underwater terrain where the missing Malaysia Airlines flight might be located, could shed additional light on what type of underwater vehicles might be used to find the missing airplane and where any debris from the crash might lie.
New research has provided scientists with greater insight into the climatic changes happening in the upper atmosphere. Scientists found that changes in the Earth's magnetic field are more relevant for climatic changes in the upper atmosphere (about 100-500 km above the surface) than previously thought.
