NOAA satellites helped save 253 people last year

17 January 2014

The same NOAA satellites that helped forecasters predict severe weather, such as the Moore, Okla., tornado last May and November's deadly Midwest tornado outbreak, also played a key role in rescuing 253 people from potentially life-threatening scenarios throughout the United States and its surrounding waters last year.

DLR satellite data helps in the rescue of the Akademik Shokalskiy

DLR satellite data helps in the rescue of the Akademik Shokalskiy

For ten days, 74 scientists and tourists were trapped in the Antarctic on board the Russian Akademik Shokalskiy research vessel. Strong winds had driven ice floes into a bay, blocking the ship's advancement. High-resolution satellite data provided by the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) helped to assess the ice conditions at the location.

In pack ice, the situation can change quickly when the wind shifts. This is why researchers from the DLR Earth Observation Center (EOC) use up-to-date, high-resolution images from the Earth observation satellite TerraSAR-X to provide the crew of the research vessel with up-to-date information regarding the ice conditions. The German radar satellite operates in a variety of modes to permit imaging with varying swathe widths, resolutions and polarisations.

Seeing through clouds and darkness, the satellite is able to observe the ocean and frozen waters from an altitude of around 500 kilometres, providing a swathe width of 30 kilometres. To do this, it emits microwaves that are reflected back to the satellite in a way that depends on the characteristics of the reflecting surface. The technology provides an extremely high resolution of down to three metres. This is crucial, as the ice structure may change greatly over just a few hundred metres. The satellite data provides scientists with a high-resolution image of the surface of the ice.

The Group on Earth Observations looks toward a second decade of data sharing

06 January 2014

The image that best captures the raison d'etre of the Group on Earth Observations (GEO) - which is holding its 10th plenary in Geneva, Switzerland, this month - is not a satellite image. Strictly speaking, the image doesn't even fall into the category of Earth observation; it is a rather ordinary looking graph from a PowerPoint presentation used by Barbara J. Ryan, director of the GEO Secretariat, at a workshop hosted by the International Society for Photogrammetry and Remote Sensing in Ankara, Turkey, in November.
