Waldbrände in den USA
18. September 2020
Die Waldbrände der letzten Tage in den USA gelten als die schwersten seit Aufzeichnung.
Über mehrere tausend Kilometer erstrecken sich die Rauchfelder in den MODIS-Aufnahmen der Satelliten Terra und Aqua. Auch in Deutschland ließen sich die Rauchpartikel messen. Sie führten hier zu spektakulären Sonnenauf- und Untergängen, da die Rauchpartikel blaues Licht stärker filtern und vermehrt rotes Licht durchlassen.
Anniversary in the Arctic Circle - A decade of satellite data reception in Inuvik
When the Sun is shining and there is no wind, Inuvik’s annual average temperature of minus 10 degrees Celsius does not seem so bad. But when the weather turns, the Arctic reveals its true nature. Storm clouds gather in the infinite blue sky, gusts of wind blow a gale, and buildings and vegetation vanish into the white vastness within minutes. In winter, the temperature can drop to as low as minus 45 degrees Celsius. During the short summer, clouds of mosquitoes billow from the countless puddles, ponds and lakes. With temperatures rising up to 30 degrees Celsius, the permafrost is transformed into a slushy morass. Why on Earth would anyone want to set up a ground station here?

Noctilucent clouds over Bavaria
07 July 2020
After sunset these past few days we were offered a spectacle quite unusual at our latitudes. Although the sun had already retreated below the horizon, silvery cloud structures became visible, so-called “noctilucent clouds”. Noctilucent clouds are not conventional clouds and thus of considerable interest to scientists. They are visible ambassadors of the climate change that is under way. .

Unusual ozone hole over the Artic
25 March 2020
We got used to the fact that an ozone hole appears every year in the Antarctic spring. Due to special meteorological conditions this spring a similar effect is observed over the northern polar region. The ozone hole is caused by the combination of temperatures below -80°C, sunlight, and ozone depleting substances (ODS). In contrast to the Antarctic, the Artic polar vortex in the spring is less stable and the temperatures inside the vortex are relative warm.

30 January 2020
At Gars O’Higgins in the Antarctic there was good reason to celebrate. The German radar satellite TerraSAR-X orbited the earth for the 70,000th time. Among other places, its data are acquired at the German Gars O’Higgins receiving station that is operated by DLR and the Federal Agency for Cartography and Geodesy and supported year-round by EOC staff.
BLOG: With Agulhas II into "perennial ice"
Progress report part 1 - 6
It began toward the end of September 2019 in a discussion with Dr. Christine Wesche of the Alfred Wegener Institute (AWI). The idea of using a supply trip by the icebreaker S.A. Agulhas II to the AWI Antarctic station to conduct some research at the same time evolved in a few weeks with the support of DLR, AWI, and not least also my family, into a concrete plan. After the obligatory medical check-up and instruction about environmental protection in the Antarctic we were to head toward South Africa already in mid-January.

Smart data for sustainable cities
20 January 2020
Earth observation and artificial intelligence can be used to assist with sustainable development decisions. Some years ago, Earth underwent an epochal change, albeit one that was consciously perceived by only a few of us. For the first time in human history, more people are living in cities than in rural areas. Although this might not seem particularly remarkable at first glance, this change will ultimately affect each and every one of us, whether directly or indirectly – because the future is urban.

15 January 2020
Aerial remote sensing supplements earth observation from space and contributes to the development of new satellite instruments and analytic methodologies. The cameras in use so far at EOC are now being replaced by new, improved instruments. They are available to all DLR scientists and their cooperating partners via the EOC user-service Optical Airborne Remote Sensing (OpAiRS).
Ice pilot: EOC sea ice analyses for maritime navigation in Arctic waters
14 January 2020
Sea ice can be dangerous for ships. If it is shoved together by storms, pressure ridges several metres thick can form, invincible even for icebreakers. EOC is working on methodologies for distinguishing types of sea ice and monitoring their drift to identify where potential pressure ridges could form. For this purpose EOC scientists rely on radar images that provide a picture of the ice situation regardless of cloud cover or polar night. For the analysis near Price Patrick Island in Canada shown here a time series recorded by the German radar satellite TerraSAR-X was used.
