Overview

Randomized trial improves precision of gravity field models using advanced data integration.

Key Points

  • The aim is to reduce errors in gravity field solutions and improve error estimates for consistency in multi-mission data.
  • Utilized updated data from GRACE V05 L1B and reprocessed GOCE V202.
  • Incorporated pseudo surface gravity data for enhanced model accuracy.
  • Developed the GIF63 model as an intermediate representation in the re-processing efforts.
  • Achieved a more accurate monthly gravity field solution compared to previous models.
  • Significantly improved fidelity of error estimates in the GIF63 model.
