Annual National Radio Science Meeting (NRSM)

USNC-URSI organizes an annual National Radio Science Meeting (NRSM) in Boulder, CO every January. In 2024, we celebrated the 50th anniversary of this event being held in Boulder, CO. The NRSM is sponsored by the U.S. National Committee (USNC) for the International Union of Radio Science (URSI), and it is technically cosponsored by the IEEE Antennas and Propagation Society. The program typically includes a plenary session, workshops/short courses, exhibits, a student paper competition, an invited Hans Liebe Lecturer, and a student mentoring luncheon.

Information and recordings of the previous Hans Liebe Lectures Hans Liebe Lectures may be viewed, along with many of the previous plenary session talks and other events held during the NRSM. Additionally, information about past NRSM programs is available.
