CHAMP

Challenging Minisatellite Payload

Subject(s)
Content type(s)
Country
CHAMP (CHAllenging Minisatellite Payload) is a German small satellite mission for geoscientific and atmospheric research and applications, managed by GFZ. With its highly precise, multifunctional and complementary payload elements (magnetometer, accelerometer, star sensor, GPS receiver, laser retro reflector, ion drift meter) and its orbit characteristics (near polar, low altitude, long duration) CHAMP will generate for the first time simultaneously highly precise gravity and magnetic field measurements over a 5 years period. This will allow to detect besides the spatial variations of both fields also their variability with time. The CHAMP mission had opened a new era in geopotential research and had become a significant contributor to the Decade of Geopotentials. In addition with the radio occultation measurements onboard the spacecraft and the infrastructure developed on ground, CHAMP had become a pilot mission for the pre-operational use of space-borne GPS observations for atmospheric and ionospheric research and applications in weather prediction and space weather monitoring. End of the mission of CHAMP was at September 19 2010, after ten years, two month and four days, after 58277 orbits.

Country
<<<<< ----- !!! The data is in the phase of migration to another system. Therefore the repository is no longer available. This record is out-dated.; 2020-10-06 !!! ----- >>>>> Due to the changes at the individual IGS analysis centers during these years the resulting time series of global geodetic parameters are inhomogeneous and inconsistent. A geophysical interpretation of these long series and the realization of a high-accuracy global reference frame are therefore difficult and questionable. The GPS reprocessing project GPS-PDR (Potsdam Dresden Reprocessing), initiated by TU München and TU Dresden and continued by GFZ Potsdam and TU Dresden, provides selected products of a homogeneously reprocessed global GPS network such as GPS satellite orbits and Earth rotation parameters.

Subject(s)
Content type(s)
Country
>>>!!!<<< The repository is no longer available. >>>!!!<<< C3-Grid is an ALREADY FINISHED project within D-Grid, the initiative to promote a grid-based e-Science framework in Germany. The goal of C3-Grid is to support the workflow of Earth system researchers. A grid infrastructure will be implemented that allows efficient distributed data processing and inter-institutional data exchange. Aim of the effort was to develop an infrastructure for uniform access to heterogeneous data and distributed data processing. The work was structured in two projects funded by the Federal Ministry of Education and Research. The first project was part of the D-Grid initiative and explored the potential of grid technology for climate research and developed a prototype infrastructure. Details about the C3Grid architecture are described in “Earth System Modelling – Volume 6”. In the second phase "C3Grid - INAD: Towards an Infrastructure for General Access to Climate Data" this infrastructure was improved especially with respect to interoperability to Earth System Grid Federation (ESGF). Further the portfolio of available diagnostic workflows was expanded. These workflows can be re-used now in adjacent infrastructures MiKlip Evaluation Tool (http://www.fona-miklip.de/en/index.php) and as Web Processes within the Birdhouse Framework (http://bird-house.github.io/). The Birdhouse Framework is now funded as part of the European Copernicus Climate Change Service (https://climate.copernicus.eu/) managed by ECMWF and will be extended to provide scalable processing services for ESGF hosted data at DKRZ as well as IPSL and BADC.
