Data and Models
Assimilative Upper Atmosphere Model TIE-GCM PDAF
Earth’s upper atmosphere begins at roughly 90 km altitude and is an ionized gas mixture whose state is strongly influenced by solar radiation and solar wind. It is also coupled to Earth’s magnetosphere, plasmasphere, and the lower atmosphere.
Land TWSA Forecasting
Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its successor mission GRACE Follow-On (GRACE-FO) have provided critical insights into terrestrial water dynamics by measuring total water storage anomolies (TWSA) across the globe.
IGG-SLR-HYBRID
IGG-SLR-HYBRID is a series of high-resolution monthly gravity fields from satellite laser ranging (SLR) to five satellites (Lageos 1 and 2, Stella, Starlette, Ajisai). It applies a novel approach in which the temporal changes of the gravity field are represented by the leading empirical orthogonal functions (EOFs) from the GRACE time series.
TUDaBo a SAR Mode Processing Prototype for G-POD Altimetry Coastal and Open Ocean Performance
TUDaBo SAR-RDSAR (Technical University Darmstadt – University Bonn SAR-Reduced SAR), is a processor prototype developed to experiment with SAR mode data from L1A (FBR) to L2.
GRACE Level-3 Monthly Solution
Equivalent water heights (EWH) are derived from monthly level-2 solutions of the Gravity Recovery and Climate Experiment (GRACE) satellite mission and of the GRACE-Follow On satellite mission, by relating changes in gravity to changes in the mass distribution in a thin surface layer, loading the Earth elastically.
Time series of ocean mass change from GRACE
The Gravity Recovery And Climate Experiment (GRACE) mission has measured mass change in the Earth's water cycle between 2002 and 2017 and it is continued by the GRACE-FO mission which has successfully been launched in May, 2018.
Time series of ocean mass change from Swarm
Swarm is a multi-satellite mission within the Earth Explorer Opportunity Program of the European Space Agency (ESA) with the primary purpose to study the Earth's geomagnetic field. The three satellites, Swarm A, B and C, were launched into a near-polar low Earth orbit on 22 November 2013
LRO orbit
Since 2009, the Lunar Reconnaissance Orbiter (LRO) explores the lunar surface by images and altimetric ranges. Referring these observations to a Moon-fixed reference frame requires highly accurate and consistent orbits.
Geocenter loading coefficients
Geocenter motion and surface loading coefficients from a joint inversion of GPS, GRACE and Ocean Bottom Pressure from a model.
Atmospheric De-aliasing
A new series of 6-hourly atmospheric de-aliasing products based on reanalysis (ITG3D-ERA-Interim) - coverage: 2003-2011.5
