We carry out a comprehensive error assessment of Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GFO) Release-6 (RL06) solutions from the Center for Space Research (CSR) at University Texas Austin, NASA Jet Propulsion Laboratory (JPL), Geoforschungszentrum (GFZ). The study covers period April 2002 to August 2020 uses two different methods, one based upon open ocean residuals (O...

When I was first in practice I had a patient, a university student, who developed strep throat. Because he was allergic to penicillin, I prescribed him a course of erythromycin. He came back to see me after he had completed the antibiotics. I was shocked by his appearance. He was pale, had dark circles under his eyes, and had lost a substantial amount of weight. He looked far worse than when he...

In this paper we critically analyze the so far performed and proposed tests for measuring the general relativistic Lense-Thirring effect in the gravitational field of the Earth with some of the existing accurately tracked artificial satellites. The impact of the 2nd generation GRACE-only EIGEN-GRACE02S Earth gravity model and of the 1st CHAMP+GRACE+terrestrial gravity combined EIGEN-CG01C Earth...
