Validation of GRACE/GRACE-FO Solutions Using Caspian Sea Level Change

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
To validate gravity recovery and climate experiment (GRACE)/ GRACE follow-on (GRACE-FO) gravity solutions, we compare satellite altimetry observations of Caspian Sea level (CSL) change with CSL estimates from satellite gravity from April 2002 to ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Advancements in the GRACE and GRACE‐FO Gradiometer Mode

open access: yesEarth and Space Science
AbstractThe global gravitational gradient field has not been observed since the decommission of GOCE in 2013. Based on the foundational work of Peidou and Pagiatakis (2019, https://doi.org/10.1029/2018jb016382), we advance the concept of GRACE gradiometer mode (GM) for the purpose of using GRACE, GRACE‐FO and future gravity space missions as ...
