IP4: Optimized Space-Time Parameterization for GRACE and GRACE-FO Data Analysis (OSTPAGA)

PIs: Roland Pail (TUM), Frank Flechtner (TUB)

Research Objectives

  1. Analyse systematic and stochastic instrument errors & derive stochastic models
  2. Optimize parameter models to describe spatio-temporal signals
  3. Adequate treatment of background model errors
  4. Numerical study of individual ingredients and their interplay, quantification of gain w.r.t. classical processing schemes
  5. 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
