Regularizing GRACE mascon solutions using river run-off data

Accurate estimates of terrestrial water storage variations (TWSV) are critical for a variety of applications, e.g., model calibration and climate studies. This study aims to find the added value of river run-off data for regularizing GRACE mascon solution, from which TWSV can be estimated. Most subbasins of the Mississippi Basin show an...

Analysis of noise in K-Band Ranging data: An investigation of noise in KBR ranging data of NASA’s and GFZ’s GRACE Follow-On mission. Detection of outliers and estimation on the noise power spectral density.

The GRACE Follow-On mission is using classical K-Bandranging (KBR) and a new laser-ranging interferometry (LRI) method. The lattergives ranging data two orders of magnitude more accurate compared to theclassical K-Band ranging data <i>(Dahl C et al. 2016). </i>This gives a newopportunity for analyzing KBR noise by...

A comparison of physics-based model computed and GNSS observed vertical land displacement of Greenland

By combining the RACMO2.3 RCM output with GRACE non-tidal ocean and atmospheric pressure anomaly as well as geo-center motion corrections from 2003 to 2017, a physics-based model to estimate the vertical displacement of the Greenland surface bedrock is created. This model is able to convert the mass and pressure anomalies into vertical...

A SAR-derived long-term record of glacier evolution in North-West Greenland

Observations show that the Greenland ice sheet is losing mass with accelerating pace. Ice discharge trough outlet glaciers contributes approximately for half of the mass loss. However, the role of marine-terminating outlet glaciers on the response of the Greenland ice sheet to climate change is relatively unknown. In recent years, observations...
