Tandem-L – A Satellite Mission for Monitoring Dynamic Processes on the Earth’s Surface
Tandem-L is a proposal for a highly innovative satellite mission for the global observation of dynamic processes on the earth’s surface with hitherto unknown quality and resolution. Thanks to the novel imaging techniques and the vast recording capacity, Tandem-L will provide urgently needed information for solving pressing scientific questions in the areas of the biosphere, geosphere, cryosphere, and hydrosphere. Tandem-L will make a vital contribution towards a better understanding of the earth system and its dynamics.
How researchers use the latest Earth observation data - Part 3
20 October 2016
Part three of this blog series looks into our dynamic Earth: How is it changing, at what speed and with what consequences? The satellite missions TerraSAR-X and TanDEM-X offer new perspectives, which inspire scientists to take new approaches.
How researchers use the latest Earth observation data - Part 2
19 October 2016
In the second part of the series on the TerraSAR-X and TanDEM-X Science Meeting in Oberpfaffenhofen, we present further applications for satellite data. This time, for example, biomass is determined with the help of 'Earth observers from space'. Up until Thursday, 20 October 2016, international scientists will use the congress to show their research results on satellite-based Earth observation and to exchange ideas.
How researchers use the latest Earth observation data - Part 1
19 October 2016
Researchers from across the globe are in Oberpfaffenhofen for the TerraSAR-X and TanDEM-X Science Meeting. For four days, from 17 to 20 October 2016, they have the opportunity to present their results from the data acquired by the two Earth observation satellite missions and exchange information. Here, approximately 200 presentations give an overview of the latest research in satellite-based Earth observation. The radar data are used in various scientific fields, from climate research to geosciences to forestry, infrastructure planning and remote sensing methodology.
The future of radar – scientific benefits and potential of TerraSAR-X and TanDEM-X
17 October 2016
The German satellite duo TerraSAR-X and TanDEM-X have consistently delivered one-of-a-kind Earth observation data since 2007 and 2010, hence shaping the international research landscape. Now, scientific users from across the globe have gathered for the TerraSAR-X and TanDEM-X Science Meeting at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Oberpfaffenhofen, where they will discuss the results obtained from the data and define requirements for future remote sensing technology.
Next TerraSAR-X/TanDEM-X Science Team Meeting: October 17-20, 2016 at DLR in Oberpfaffenhofen, Germany
20 July 2016
The main goal of the meeting is the presentation of results, exchange of experiences and the information about the TerraSAR-X, TanDEM-X and Tandem-L mission status. Interested scientists are kindly invited to present their research results in an oral or poster presentation. Preliminary programs, registration, hotel, and general information on the TerraSAR-X, TanDEM-X and Tandem-L workshop can be found on the

DLR Magazin 148 - Remote Sensing 4.0
14 April 2016
Six years after its launch, the TanDEM-X radar satellite mission will achieve its primary mission objective. A digital elevation model of the Earth with unprecedented accuracy is now more than 90 percent complete and available for use by the international scientific community.
Focus on Gabon Forests for BIOMASS
03 March 2016
The DLR German Aerospace Center’s AfriSAR field team leader, Ralf Horn, said, “Everything went smoothly and the radar measurements are of excellent quality. The biggest challenge we faced was the weather, but most of the rain fell during the night and we were able to fly above the clouds.”
Germany's radar eyes in space
22 February 2016
In a formation flight, the German Aerospace Center's satellite twins are mapping the earth in 3-D. Their images make us wonder today: The run of Budapest's new metro tube, line 4, can be seen from space (

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

Greenland's glaciers are melting - DLR satellites provide data for new long-term study
12 November 2015
IN GERMAN: Bislang galten die Gletscher im Nordosten Grönlands wegen der starken Kälte als sicher vor der Klimaerwärmung. Ein Forscherteam der amerikanischen University of California, Irvine (UCI) konnte nun jedoch in einer Langzeitstudie am Gletscher Zachariæ Isstrøm zeigen, dass die riesigen Eismassen schneller schmelzen als bisher angenommen.
DLR/NASA – 3D radar measurements of forest areas
15 July 2015
The radar experts at DLR partnered with the US aerospace agency NASA in a measurement campaign, which has now confirmed the capability of the F-SAR system. The cooperation was aimed at validating the suitability of the radar data to infer a variety of parameters, including a forest’s height or vertical structure.

F-SAR Greenland Campaigns "ARCTIC15" and "DALOEX15"
13 May 2015
ARCTIC15 is a campaign promoted by the Microwaves and Radar Institute of the German Aerospace Center (DLR), carried out in cooperation with the Danish Defence Acquisition and Logistics Organization (DALO) as well as ETH Zurich, and with the support of the Alfred Wegener Institute (AWI). It takes place in Greenland from mid-April to end-May 2015 with the objective of collecting polarimetric-interferometric SAR data at different frequencies (X-, C-, S-, L- and P-band) over different facies of the ice sheet, while the objective of the DALO part of the campaign (DALOEX 2015) is to explore the possibilities that advanced SAR systems provide for surveillance etc. in Arctic scenarios.

Radar remote sensing: Research for acriculture and climate
19 September 2014
IN GERMAN: Das Erntejahr 2014 nähert sich dem Ende und in ganz Deutschland zeichnen sich für Weizen, Mais & Co. insgesamt gute Erträge ab. Standortabhängig zeigen sich jedoch extreme Unterschiede. Für optimalen Anbau ist es daher wichtig, den Zustand des Bodens und der Pflanze stets zu kennen. Radaraufnahmen sind besonders gut geeignet, flächendeckende Beobachtungen durchzuführen – per Flugzeug oder per Satellit.
