Short-Term and Long-Term Replenishment of Water Storage Influenced by Lockdown and Policy Measures in Drought-Prone Regions of Central India

Remote Sensing, 2022
Central India faces a freshwater shortage due to its diverse terrain, sudden change in precipitation patterns and crystalline rock covered subsurface. Here, we investigate the patterns in terrestrial water storage anomaly (TWSA) over the last two decades,

Autoregressive Reconstruction of Total Water Storage within GRACE and GRACE Follow-On Gap Period

Energies, 2022
For 15 years, the Gravity Recovery and Climate Experiment (GRACE) mission have monitored total water storage (TWS) changes. The GRACE mission ended in October 2017, and 11 months later, the GRACE Follow-On (GRACE-FO) mission was launched in May 2018 ...

In-Orbit Performance of the GRACE Follow-on Laser Ranging Interferometer [PDF]

Physical Review Letters, 2019
The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degrees of ...

On the co-estimation of static and monthly gravity field solutions from GRACE Follow-On data [PDF]

, 2023
Temporal gravity field modelling from GRACE Follow-On data is usually performed by computing monthly snapshots of spherical harmonic coefficients representing the state of the Earthâ?Ts gravity field. Associated to this, the spherical harmonic series has

Scale Factor Determination for the GRACE Follow-On Laser Ranging Interferometer Including Thermal Coupling

Remote Sensing, 2023
The GRACE follow-on satellites carry the very first interspacecraft Laser Ranging Interferometer (LRI). After more than four years in orbit, the LRI outperforms the sensitivity of the conventional Microwave Instrument (MWI).
