Glet­scher­rück­gang in den Al­pen – erst­mals flä­chen­de­ckend do­ku­men­tiert

Ein Forschungsteam der Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) untersuchte die Flächen- und Höhenänderungen aller Gletscher der europäischen Alpen über einen Zeitraum von 14 Jahren. Dazu verglichen sie dreidimensionale Geländemodelle der deutschen Radarsatellitenmission TanDEM-X und der deutsch-amerikanischen Shuttle-Radar Topography Mission (SRTM) aus der Zeit zwischen 2000 und 2014.

Congratulations, TanDEM-X – 10 years of 3D mapping from space

A new era in radar remote sensing began 10 years ago, on 21 June 2010, when the radar satellite TanDEM-X was launched. Since then, it has been orbiting Earth in close formation flight with TerraSAR-X, its three-year-older 'twin'.

Development of the Patagonian Ice Fields reveals the enormous complexity of physical interactions

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.

Tidal glaciers in Greenland – TanDEM-X elevation models show strongest decline in 80 years

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.

TanDEM-X reveals glaciers in detail

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. [full article]

Global TanDEM-X forest map is available

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) 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 the ice – Canadian 'ice road' trucks in TanDEM-X's 'radar eye'

Ice road truckers in Canada – symbolically 'at the end of the world' – with their massive trucks travelling over the frozen lakes in the Canadian northwest, are well known around the world thanks to numerous TV programmes. The ice roads are open for only a few weeks per year. During this time, thousands of tonnes of freight are moved across these 'ice highways', as the frozen lakes in winter act as seasonal roads and provide an effective and economical way to reach remote communities and businesses in the coldest regions.

Glacier retreat in Antarctica – innovative radar technologies enable improved predictions

Thwaites Glacier, one of the most fragile glaciers in western Antarctica, is melting inexorably into the Amundsen Sea at an ever-increasing rate. Until now, it has been responsible for approximately four percent of the global rise in sea level and will cause the oceans to rise by over 65 centimetres in future as its remaining ice melts. With the German radar satellites TerraSAR-X and TanDEM-X, it is now possible, for the very first time, to observe Thwaites Glacier and other polar regions at regular intervals, with high resolution and in three dimensions.

Global 3D elevation model from the TanDEM-X mission now freely available

The 90-metre TanDEM-X Digital Elevation Model has been released for scientific use and is now available as a global dataset. By providing this data, the German Aerospace Center follows the EU data policy under the Copernicus Earth observation programme, which encourages free and open access to satellite data.
