IP4: Optimized Space-Time Parameterization for GRACE and GRACE-FO Data Analysis (OSTPAGA)
PIs: Roland Pail (TUM), Frank Flechtner (TUB)
Research Objectives
- Analyse systematic and stochastic instrument errors & derive stochastic models
- Optimize parameter models to describe spatio-temporal signals
- Adequate treatment of background model errors
- Numerical study of individual ingredients and their interplay, quantification of gain w.r.t. classical processing schemes
- Quantify gain of LRI vs. KBR
Innovations
- Method development based on interaction of numerical closed-loop simulation and real data analysis
- Gain of in-depth understanding of all ingredients of the gravity retrieval process, and their coupling, and quantification of impact in ideal and real world
