TanDEM-X Earth observation mission: Tidal glaciers in Greenland – TanDEM-X elevation models show strongest decline in 80 years

13 September 2019
The Kangerlussuaq Glacier is the largest glacier on the southeast coast of Greenland and flows into the fjord of the same name. The glacier front, which in the past was protected by an ice mélange – a mixture of sea ice and calved icebergs – is retreating at an increasing rate. The glacier calves approximately 24 cubic kilometres of ice into the ocean every year. This corresponds to about five percent of the amount of ice lost annually by the entire Greenland ice sheet. Using a time series of 150 TanDEM-X elevation models of the Kangerlugssuaq Glacier, scientists from Swansea University in the United Kingdom have measured the decrease in the glacier’s surface height.

South America: TanDEM-X reveals glaciers in detail

12 June 2019
A precise understanding of glacier evolution requires knowledge of a glacier's exact mass. This is important in South America, in the tropical regions between Bolivia and Venezuela, where meltwater from glaciers provides drinking water during the dry season. However, basic data about mass changes in glaciers are not easy to obtain. Mass losses are also contributing to rising sea levels on a global scale. As a new analysis method using TanDEM-X data shows, this is particularly true for Patagonia.

TERRA_Byte – Top computing power for researching global change

27 May 2019
One of Europe's largest supercomputing centres – the Leibniz Computer Centre (LRZ) of the Bavarian Academy of Sciences – and Europe's largest space research institution – the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) – will work together to evaluate the vast quantities of data acquired by Earth observation satellites alongside other global data sources, such as social networks, on the state of our planet on a daily basis.

Global TanDEM-X forest map is available

06 May 2019
Forests are Earth's lungs; they help to reduce greenhouse gas concentrations in the atmosphere and thus counteract global warming, while also providing protection and resources for humans, animals and plants – and they are being lost at an alarming rate. As the view from space reveals, forests cover about one third of Earth’s landmass today. More than half of the world’s forests, which have fallen victim to deforestation since the middle of the 20th century in particular, have already been lost. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), Microwaves and Radar Institute (HR) has created a special dataset to monitor, assess, and protect the current state and development of this green organ with precision – the global TanDEM-X Forest/Non-Forest Map.

Waves on ice - "Radar Eye" TanDEM-X monitors trucks on ice roads

13 March 2019
IN GERMAN: Eine Studie vom Canada Centre for Mapping and Earth Observation untersuchte den Nutzen von TanDEM-X für die Unterstützung des Eisstraßenmanagements mit Fokus auf den nordwestlichen Territorien Kanadas. Dabei entstand aus zwei TanDEM-X-Datensätzen eine Abbildung, auf der wellenförmige Hebungen und Senkungen einer Eisdecke zu erkennen sind. Ursache sind die Ice Road Trucks, die in den Wintermonaten über die gefrorenen Seen in Kanada transportieren.

Glacier shrinkage in Antarctica: Better Predictions thanks to innovative radar technologies

01 February 2019
IN GERMAN: Der Thwaites Gletscher gehört zu den fragilsten Gletschern der Westantarktis und schmilzt mit zunehmender Geschwindigkeit unaufhaltsam in die Amundsen See. Bislang ist er für rund vier Prozent des globalen Meeresspiegelanstiegs verantwortlich und kann mit seinen verbleibenden Eismassen die Ozeane künftig um mehr als 65 Zentimeter steigen lassen. Mithilfe der deutschen Radarsatelliten TerraSAR-X und TanDEM-X ist es erstmals möglich, den Thwaites Gletscher und andere Polgebiete flächendeckend mit hoher Auflösung dreidimensional zu vermessen und regelmäßig zu beobachten.

Season´s Greetings and wishes from TanDEM-X!

23 December 2018
All people living in the world today are descended from Africans who left the continent at least 100,000 years ago. Those who stayed behind continued to innovate and develop their knowledge and ideas. The TanDEM-X image above shows the topography of Cape Town and its surroundings. Table Mountain, a well-known landmark of the city, is seen just south of the harbor area. The Cape Town region is characterized by an extensive coastline, rugged mountain ranges, coastal plains, inland valleys and semi-desert fringes.

TanDEM-X was launched in 2010 and has been operating together with its twin TerraSAR-X as a bistatic SAR interferometer since the beginning of 2011. The global digital elevation model of TanDEM-X became available in 2016 and surpassed all expectations. It has 99.9% coverage, 12-m posting, absolute height accuracy of approximately 1 m. This unique data set has been available since then for commercial and scientific applications. This year, the low-resolution version of the TanDEM-X digital elevation model with 90-m posting has been released for free download for scientific applications.

Claudia Roth, Member of the Bundestag, visits HR Institute

20 December 2018
Climate research and remote sensing have been the topics when Claudia Roth, Member of the Bundestag, the German parliament, came to the German Aerospace Center (DLR) on 20 December 2018. One of five stations in DLR was a short visit at our Institute. Amongst other things, she also informed herself about TanDEM-X and the anticipated Tandem-L SAR satellite mission, initiated by the HR Institute. Tandem-L will provide, in weekly rhythm, latest data to dynamically running processes on the Earth surface.
