2019 National Radio Science Meeting in Boulder, Colorado
The 2019 NRSM, sponsored by the USNC-URSI, was held Wednesday through Saturday, 9-12 January, in Boulder, CO. The URSI-URSI supported the travel of 109 students going to the 2019 NRSM.

A special Historical Lecture was given by Dr. Anthea Coster, of MIT Haystack Observatory, in Westford, MA. Her talk, titled “Lise Meitner: Her Escape from Germany and The Discovery of Fission,” was the first of its kind at the NRSM, and gave an account of this fascinating story that involved Dr. Coster’s grandfather.
The latest Hans Liebe Lecture was given at the 2019 NRSM by Dr. Domenico Cimini of the Institute of Methodologies for Environmental Analysis (CNR-IMAA) in Potenza, Italy. His talk, titled "Fostering Ground-Based Microwave Radiometry: From Uncertainty to Networking," was sixth in the series. Click here for more information on the Hans Liebe Lecture series.
