Significant advances in the scientific use of space based data were achieved in three joint interdisciplinary projects based on data of the satellite missions CHAMP, GRACE and GOCE within the R&D program GEOTECHNOLOGIEN. It was possible to explore and monitor changes related to the Earth’s surface, the boundary layer between atmosphere and solid earth, and the oceans and ice shields. This boundary layer is our habitat and therefore is in the focus of our interests. The Earth’s surface is subject to anthropogenetic changes, to changes driven by the Sun, Moon and planets, and by changes caused by processes in the Earth system. The state parameters and their changes are best monitored from space. The theme “Observation of the System Earth from Space” offers comprehensive insights into a broad range of research topics relevant to society including geodesy, oceanography, atmospheric science (from meteorology to climatology), hydrology and glaciology.

This book is a collection of overview articles showing how space-based observations, combined with hydrological modeling, have considerably improved our knowledge of the continental water cycle and its sensitivity to climate change. Two main issues are highlighted: (1) the use in combination of space observations for monitoring water storage changes in river basins worldwide, and (2) the use of space data in hydrological modeling either through data assimilation or as external constraints. The water resources aspect is also addressed, as well as the impacts of direct anthropogenic forcing on land hydrology (e.g. ground water depletion, dam building on rivers, crop irrigation, changes in land use and agricultural practices, etc.). Remote sensing observations offer important new information on this important topic as well, which is highly useful for achieving water management objectives.Over the past 15 years, remote sensing techniques have increasingly demonstrated their capability to monitor components of the water balance of large river basins on time scales ranging from months to decades: satellite altimetry routinely monitors water level changes in large rivers, lakes and floodplains. When combined with satellite imagery, this technique can also measure surface water volume variations. Passive and active microwave sensors offer important information on soil moisture (e.g. the SMOS mission) as well as wetlands and snowpack. The GRACE space gravity mission offers, for the first time, the possibility of directly measuring spatio-temporal variations in the total vertically integrated terrestrial water storage. When combined with other space observations (e.g. from satellite altimetry and SMOS) or model estimates of surface waters and soil moisture, space gravity data can effectively measure groundwater storage variations. New satellite missions, planned for the coming years, will complement the constellation of satellites monitoring waters on land. This is particularly the case for the SWOT mission, which is expected to revolutionize land surface hydrology. Previously published in Surveys in Geophysics, Volume 37, No. 2, 2016

Das Handbuch der Geodäsie ist ein hochwertiges, wissenschaftlich fundiertes Werk über die Geodäsie unserer Zeit und bietet anhand von in sechs Bänden zusammengestellten Einzelthemen ein repräsentatives Gesamtbild des Fachgebiets. Satelliten führten zu einer Revolution in der Geodäsie. Erst mit Hilfe von Satelliten wurde die Erdmessung tatsächlich global und dreidimensional. Ozeane und Eisschilde stellen keine Hindernisse mehr dar, sie lassen sich heute mit gleicher Präzision vermessen wie die Kontinente. Verfeinerungen resultieren aus der Kombination von Raumverfahren mit terrestrischen Messmethoden. Damit gelingt es der Erdmessung, fundamentale Beiträge zum Verständnis des Erdsystems und des Klimawandels zu liefern. Voraussetzung für diese Entwicklung sind sehr moderne Messverfahren und Auswertemethoden und deren extrem genaue Verknüpfung in einem globalen erd- und raumfesten Referenzsystem. Im Band Erdmessung und Satellitengeodäsie werden exemplarisch die historischen Wurzeln, methodischen Grundlagen, verwendeten Messverfahren sowie die Forschungstrends vorgestellt.

​Deutschland hat im internationalen Vergleich eines der zuverlässigsten Elektrizitätssysteme. Jedoch befindet sich die Elektrizitätsversorgung in einer Transformation von fossiler zu regenerativer Erzeugung. Die Kosten der Versorgungssicherheit werden aufgrund zusätzlichen Bedarfs an Investitionen in Technologien wie Backup-Kraftwerke oder Speicher zukünftig ansteigen. Welches Sicherheitsniveau ist für die verschiedenen Kunden tatsächlich gesellschaftlich optimal? Die Antwort auf diese Frage hängt davon ab, welche Kosten Verbrauchern bei Stromunterbrechungen entstehen. Unter Umständen ist es sinnvoller, Verbraucher kurzfristig abzuschalten, anstatt diese für wenige Stunden mit teuren Kraftwerken und Speichern zu versorgen. Hierfür ist aber letztlich ein breiter gesellschaftlicher Konsens hinsichtlich der Präferenzen zwischen Versorgungssicherheit, Klimaschutz und Kernenergieausstieg notwendig. Aaron Praktiknjo befasst sich in dieser Monographie mit diesen Fragestellungen und liefert wertvolle methodische und empirische Hinweise.
