Grigorios Kalimeris

Grigorios Kalimeris is a researcher at the Chair of Astronomical & Physical Geodesy within the Engineering Institute for Astronomical and Physical Geodesy at Technical University of Munich. His work focuses on satellite geodesy and Earth gravity field analysis, with particular expertise in processing data from the GRACE-FO mission.

His research interests center on Earth gravity field modeling, with specific focus on the impact of Laser Ranging Interferometer (LRI) technology on gravity field solutions. His work examines how LRI measurements affect the high-frequency domain and higher harmonic degrees of static Earth gravity field models, contributing to improved understanding of Earth's mass distribution and its temporal variations.

Dr. Kalimeris' publication record shows a consistent trajectory of research from 2022 through 2025, with multiple conference presentations at major geodetic events including the IAG Scientific Assembly and IUGG General Assembly. His work demonstrates increasing sophistication in analyzing the interplay between different instrument systems on the GRACE-FO mission.

He is actively involved in several major research initiatives including the DFG Research Unit NEROGRAV, DFG Research Training Group UPLIFT, and multiple ESA projects (Baltic+ Project Theme 5, MAGIC/Science, and QSG4EMT). These projects focus on advancing geodetic techniques for Earth observation and gravity field modeling.

Dr. Kalimeris serves as a supervisor for graduate students, currently guiding Master's research including Shirui Yan's 2025 thesis on GRACE-FO Line-of-Sight Gravity Differences. His research has practical applications for monitoring Earth system mass variations related to climate change and geophysical processes.
