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...
