Earth observation using radar interferometry: Development of the Patagonian Ice Fields reveals the enormous complexity of physical interactions

10 December 2019
The glaciers and ice fields in the South American region of Patagonia have been in retreat since the Little Ice Age between the early 14th century and the mid-19th century. In recent decades, the loss of ice masses associated with tropospheric warming has accelerated. From 2000 to 2016 the Patagonian Ice Fields contributed approximately six percent to the eustatic sea level rise of 0.74 millimetres per year.

25th Anniversary of the Space Shuttle Missions SIR-C/X-SAR

07 October 2019
Earth observers like to 'look' at the Earth with radar sensor systems. They allow high-precision images of the surface and have a great advantage over optical cameras: images can be taken not only in excellent visibility, but also in cloudy conditions, rain or at night. Research into space-based radar technologies has a long history. A milestone was the multi-frequency radar system SIR-C/X-SAR. 25 years ago, the Space Shuttle Endeavour flew around the world twice, in April and October 1994. It was the most advanced civil radar in Earth orbit at that time – and for Earth observation it was as big a step as the transition from black-and-white to colour film in photography.

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

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.

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.

DLR BLOG: TerraSAR-X monitors the "Larsen C" ice shelf break-apart

25 July 2017
IN GERMAN: Wir haben in den letzten Tagen viel in den Medien über den riesigen Eisberg lesen können, der sich am Larsen-C-Schelfeis an der Antarktischen Halbinsel gelöst hat. Dass Eisbergabbrüche von Eisschelfen natürliche Vorkommnisse sind und diese in der Antarktis immer wieder vorkommen, wurde in den Medienberichten richtig dargestellt. Und doch war dieses Ereignis präsenter als die bisherigen. Woran liegt das? Vermutlich daran, dass wir Wissenschaftler seit Monaten mithilfe von Satellitendaten dieses Gebiet der Antarktis verstärkt beobachten und regelrecht darauf gewartet haben, dass es endlich passiert. Außerdem ist diesmal doch ein verhältnismäßig großes Stück Eis abgebrochen, ungefähr sieben Mal so groß wie die Stadt Berlin.

Radar over the rainforest

24 February 2016
Dense rainforest, a twin-engine turbo-prop aircraft and advanced radar technology – researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are performing numerous measurement flights from 1 to 29 February 2016 over the central African country of Gabon to determine the state of the rainforest. The data obtained will help to improve climate models and better understand global warming. The campaign is being carried out in cooperation with the European Space Agency (ESA), the French National Aerospace Research Center (Office National d'Etudes et Recherches Aérospatiales; ONERA), the Gabonese Agency for the Study of and Observation from Space (Agence d'Études et d'Observation Spatiales; AGEOS) and US Space Agency NASA. ONERA already performed measurement flights in July 2015, during the dry season, while DLR and NASA will research the rainforest with three aircraft during the rainy season. The results will serve as reference data for the ESA satellite mission BIOMASS, planned for launch in 2020, and the German Tandem-L mission proposal.

Faster detection of landmines using radar

22 February 2016
Every 20 to 30 minutes, somewhere in the world, a person – often a child – steps on a landmine. It is estimated that over 100 million anti-personnel mines are buried worldwide and a further 200 to 250 million are thought to remain in military storage facilities. This means they pose a constant threat, even long after the end of a conflict. In order to facilitate the reconstruction of a country and the safe return of refugees, the ground must be cleared of concealed ordnance. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has developed a radar-based method, 'TIRAMI-SAR', that will allow for the quick, safe and cost-effective detection of landmines.

Approximately one quarter of the Northern Hemisphere contains permafrost – an area so vast it can only be regularly and comprehensively monitored through satellite remote sensing. The Lena Delta in Siberia lies in such a permafrost zone.

FRINGE'15: Ground deformation around the city of Naples

23. März 2015
Ten Sentinel-1A radar scans acquired between 7 October 2014 and 12 March 2015 were combined to create this image of ground deformation around the city of Naples, which includes the active volcanic areas of Italy’s Phlegraean Fields – or Campi Flegrei – and the Vesuvius volcano. Dark blue indicates areas that experienced an uplift of about 0.5 cm per month, while red areas show subsidence down to 0.5 per month. The purple square over the city of Naples indicates the location of the calibration point. These preliminary results are presently presented at the Fringe Workshop at ESA’s ESRIN centre for Earth observation.

Data Transmission via LTE

18 March 2015
So far, in the VABENE++ project data gets transmitted from the aircraft/helicopter to the ground via a special microwave link or an optical laser link. However, for these data links a special mobile ground station needs to be set up in the field. Now a study was carried out to investigate whether the modern mobile communication standard “Long Term Evolution” (LTE) can be used as an alternative or supplementary data transfer technique. For data reception on the ground only the already available LTE ground station infrastructure of the cellphone providers was considered.

The Microwaves and Radar Institute sends many season greetings and wishes you a Merry Christmas and a Happy New Year!

Sentinel-1A: Mexico City Subsidence

15 December 2014
ESA’s satellite Sentinel-1A now measures the subsidence of Mexico City as previously done by TerraSAR-X in 2010. Five Sentinel-1A radar scans acquired between 3 October and 2 December 2014 were combined to create this image of ground deformation in Mexico City. These preliminary results have been obtained by the Microwaves and Radar Institute in the frame of an ESA study to evaluate the interferometric performance of the Sentinel-1A satellite. The deformation is caused by ground water extraction, with some areas of the city subsiding with a deformation rate of up to 2.5 cm/month (red).

DLR Magazine: World atlas – 'made in space'

25 March 2014
In June 2007, the TerraSAR-X radar satellite was launched. It entered Earth orbit, where it flew ‘solo’ for three years until June 2010, when its twin, TanDEM-X, followed it into space. With their radar antennas pointed at Earth, they are on a mission to generate a three-dimensional elevation model of our planet. Now that the first elevation models are available for users, a true milestone has been reached on the journey towards a highly precise, three-dimensional world atlas ‘made in space’.

Fastest glacier in Greenland – DLR satellites TerraSAR-X and TanDEM-X identify speed record

04 February 2014
Since the 1990s, Jakobshavn Isbræ has been regarded as the fastest moving glacier in Greenland. According to studies carried out by researchers from the University of Washington and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), its speed is now increasing dramatically, with record figures for 2012 and 2013. High spatial and temporal resolution data acquired by the German radar satellites TerraSAR-X and TanDEM-X enabled very precise calculations of its speed. The results of the study will be released in the print version of 'The Cryosphere', an international scientific journal of the European Geosciences Union (EGU), on 7 February 2014.

TerraSAR-X data support the rescue of "Akademik Shokalskiy" in brash ice

09 January 2014
AVAILABLE IN GERMAN: Zehn Tage saßen 74 Wissenschaftler und Touristen an Bord des russischen Forschungsschiffs "Akademik Shokalskiy" in der Antarktis fest. Starker Wind hatte Eisschollen in eine Bucht getrieben und das Schiff blockiert. Hochauflösende Satellitendaten des Deutschen Zentrums für Luft-und Raumfahrt (DLR) halfen bei der Beurteilung der Eissituation vor Ort. Die Verhältnisse können sich im Packeis durch drehende Winde schnell verändern. Deshalb nutzen DLR-Wissenschaftler aus dem Earth Oberservation Center (EOC) aktuelle hochauflösende Aufnahmen des Erdbeoachtungssatelliten TerraSAR-X, um der Schiffsbesatzung des Forschungsschiffs aktuelle Informationen über die Eisverhältnisse zu liefern. Der deutsche Radarsatellit wird in verschiedenen Modi betrieben, um Aufnahmen mit unterschiedlichen Streifenbreiten, Auflösungen und Polarisationen zu ermöglichen.

TerraSAR-X image of the month – Coral Atoll Kiritimati

16 Dezember 2013
AVAILABLE IN GERMAN: Paris ist verlassen, in Polen leben 235 Menschen, und London hat immerhin 1829 Einwohner. Auf dem Atoll Kiritimati ist vieles anders - und so werden aus europäischen Großstädten oder Ländern winzige Orte. Der abgelegenen Insel im Pazifik, auf der Seefahrer James Cook mit seiner Mannschaft 1777 Weihnachten feierte, steht das Wasser buchstäblich bis zum Hals. Das Korallen-Atoll hat zwar 321 Quadratkilometer Landfläche - aber auch 324 Quadratkilometer Lagunenfläche. Treffen die bisherigen Schätzungen zu, könnte der Inselstaat Kiribati mitsamt der Insel Kiritimati etwa im Jahr 2070 aufgrund des Klimawandels und des Anstiegs des Meeresspiegels im Pazifik versinken. Für den Radarsatelliten TerraSAR-X des Deutschen Zentrums für Luft- und Raumfahrt (DLR) sieht das Atoll aus über 500 Kilometern Höhe wie eine poröse, zerbrechliche Struktur aus.

EUSAR 2014 - Organized by DLR’s Microwaves and Radar Institute

The 10th European Conference on Synthetic Aperture Radar (EUSAR) is being organized by DLR’s Microwaves and Radar Institute in the heart of Berlin. Traditionally, EUSAR's organization rotates among the four founding organizations: Fraunhofer (FHR), EADS Astrium, EADS Cassidian and DLR (HR). After EUSAR 2000 in Munich and EUSAR 2006 in Dresden we choose Berlin (Hotel Maritim at Tiergarten near Brandenburg Gate) as venue for EUSAR 2014. Over the years EUSAR has developed to the world's most renowned conference in the field of Synthetic Aperture Radar (SAR). Despite the difficult situation of travel fund shortages in traditionally strongly represented countries we received more than 400 papers for EUSAR 2014. More than 1200 reviews have been assigned and have been nearly finished by more than 150 SAR-experts from all over the world. We will soon be able to create a first, preliminary EUSAR 2014 Program and would like to thank all our reviewers for spending their precious time and support to make EUSAR 2014 a success.

Wide-angle view from space

30 August 2013
Officially, the German radar satellite TerraSAR-X should have been out of service for over a year and a half – that's how long it has exceeded its intended lifespan. But engineers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have switched the satellite, which was launched to space on 15 June 2007, to yet another mode: TerraSAR-X can now record image strips over 200 kilometres wide. "The satellite does so by sweeping this large area in multiple stages, very quickly pivoting the radar beam numerous times across the direction of flight," explains DLR mission manager Stefan Buckreuss. For example, the image of the German Bight shows the Frisian Islands from Borkum to Wangerooge and cities such as Wilhelmshaven and Bremen. This new ‘wide-angle’ mode is of particular interest to oceanographers, who will be able to use it to investigate the tidal range, changes to mudflats, shipping movements, wave patterns, ice floes and wind levels.
