Spatiotemporal Groundwater Storage Dynamics and Aquifer Mechanical Properties in the Santa Clara Valley Inferred From InSAR Deformation Over 2017–2022

Autor: Khosro Ghobadi‐Far, Susanna Werth, Manoochehr Shirzaei, Roland Bürgmann

Publikováno v: Geophysical Research Letters, Vol 50, Iss 22, Pp n/a-n/a (2023)

Abstract We used Interferometric Synthetic Aperture Radar (InSAR)‐derived vertical land motion (VLM) timeseries during 2017–2022 to examine the compounding impacts of natural and anthropogenic processes on groundwater dynamics in the Santa Clara

Groundwater Volume Loss in Mexico City Constrained by InSAR and GRACE Observations and Mechanical Models

Autor: Mohammad Khorrami, Manoochehr Shirzaei, Khosro Ghobadi‐Far, Susanna Werth, Grace Carlson, Guang Zhai

Publikováno v: Geophysical Research Letters, Vol 50, Iss 5, Pp n/a-n/a (2023)

Abstract Groundwater withdrawal can cause localized and rapid poroelastic subsidence, spatially broad elastic uplift of low amplitude, and changes in the gravity field. Constraining groundwater loss in Mexico City, we analyze data from the Gravity Re

Barystatic and steric sea level variations in the Baltic Sea and implications of water exchange with the North Sea in the satellite era

Autor: Armin Agha Karimi, Khosro Ghobadi-Far, Marcello Passaro

Publikováno v: Frontiers in Marine Science, Vol 9 (2022)

Satellite altimetry, satellite gravimetry, and in-situ subsurface salinity and temperature profiles are used to investigate the total, barystatic, and steric sea level variations in the Baltic Sea, respectively. To estimate the steric sea level, the

Multi-scale total water storage variations from fusion of GRACE and GLDAS Noah data using wavelet analysis

Autor: Khosro Ghobadi-Far, Susanna Werth, Manoochehr Shirzaei

The observations of total water storage variations (TWSV) from GRACE satellites have a coarse spatial resolution of ~300 km. Hydrological and land surface models, providing TWSV with higher spatial resolutions like 50 km, offer an opportunity to impr

Comparison of GRACE Follow-On Level-2 data from RL06 and RL06.1: Assessing the impact of the new accelerometer transplant data

Autor: Khosro Ghobadi-Far, Susanna Werth, Manoochehr Shirzaei, Bryant Loomis, Martin Horwath, Matthias Oskar Willen, Thorben Axel Döhne

The GRACE-D accelerometer data shows large bias jumps starting from 21 June 2018. The GRACE Follow-On (GRACE-FO) Science Data System (SDS) centers (CSR, JPL and GFZ) use a transplant technique applying GRACE-C accelerometer data to replace that of GR

New developments in Earth systems mass change studies with GRACE and GRACE Follow-On for monitoring of extreme events

Autor: Khosro Ghobadi-Far, Shin-Chan Han

The conventional data products from GRACE and GRACE Follow-On (GRACE-FO) are global snapshots of time-variable gravity or surface mass change, providing “average” fields of these quantities over a certain period like one month or 10 days. In this

Barystatic and steric sea level variations in the Baltic Sea by GRACE/GRACE FO mascon solutions, satellite altimetry, and in situ measurements

Autor: Armin Agha Karimi, Khosro Ghobadi-Far

The Baltic Sea is a semi-enclosed basin in northern Europe that is connected to the North Sea through the Danish Strait. We have deployed three datasets to study the barystatic and steric sea level changes in the basin. GRACE/GRACE FO mascon solution

Along-Orbit Analysis of GRACE Follow-On Inter-Satellite Laser Ranging Measurements for Sub-Monthly Surface Mass Variations

Autor: Khosro Ghobadi‐Far, Shin‐Chan Han, Christopher M. McCullough, David N. Wiese, Richard D. Ray, Jeanne Sauber, Linus Shihora, Henryk Dobslaw

Publikováno v: Journal of Geophysical Research: Solid Earth

We examined the sensitivity of GRACE Follow-On (GRACE-FO) laser ranging interferometer (LRI) measurements to sub-monthly time-variable gravity (TVG) signals caused by transient, high-frequency mass changes in the Earth system. GRACE-FO LRI provides c
