The IAG Young Authors Award 2019 is presented to Dr.-Ing. Susanne Glaser for her paper: Susanne Glaser, Rolf König, Karl Hans Neumayer, Tobias Nilsson, Robert Heinkelmann, Frank Flechtner & Harald Schuh (2019): On the impact of local ties on the datum realization of global terrestrial reference frames, Journal of Geodesy, 93: 655–667.

The paper deals with the effect of random and systematic errors and selection of local ties on the datum realization of global terrestrial reference frames. It is based on a thorough simulations study covering GPS, SLR and VLBI over many years. These investigations have widespread implications for our understanding of the errors in contemporary TRFs.

Dr. Glaser received her Doctor of Engineering (Dr.-Ing.) degree in Geodesy at Technische Universität Dresden, Germany in 2014, and currently she works as a research associate at the GFZ German Research Centre for Geosciences at Potsdam, Germany.

The IAG Young Authors Award 2020 is presented to Dr. Khosro Ghobadi-Far for his paper: Ghobadi-Far, K., Han, SC., Allgeyer, S., Tregoning, P., Sauber, J., Behzadpour S., Mayer-Guerr T., Sneeuw N. and Okal E. (2020): GRACE gravitational measurements of tsunamis after the 2004, 2010, and 2011 great earthquakes. Journal of Geodesy 94: 65. 

This paper is a first demonstration of the utility of satellite gravimetry to detect the gravitational signatures of tsunami waves from space. This study demonstrates an innovative way of applying GRACE and GRACE Follow-On data to detect transient geophysical mass changes which cannot be observed by the conventional monthly Level-2 and mascon solutions. 

Dr. Ghobadi-Far received his PhD at the University of Newcastle (Australia) in 2020 on analysis of GRACE data for developing new geophysical applications. Currently he works as a Postdoctoral Associate at the Department of Geoscience of Virginia Tech, USA.
