Dr. Greer served as a panelist on the 2024 Heliophysic Decadal Survey, Ionospheres-Themospheres-Mesospheres panel. This work collected the scientific community’s input for the direction of investment in the next 10 years.

The Coupling of Energetics and Dynamics of Atmospheric Regions (CEDAR) is is a Program funded by the National Science Foundation’s Atmospheric and Geospace Sciences Division with a mission to understand the fundamental properties of the space-atmosphere interaction region; identify the interconnected processes that define the local and global behavior, the evolution, and influence on the Sun-Earth system; and to explore the ionosphere-thermosphere predictability. Dr. Greer served on the CEDAR Science Steering Committee (CSSC) 2022-2025.

Dr. Greer regularly convenes sessions at selected conferences that focus on the near-space environment and space weather. Conferences include CEDAR and the American Geophysical Union (AGU).

Dr. Greer regularly reviews manuscripts for the Journal of Geophysical Research, including Space Physics and Geophysical Research Letters. In addition, she is frequently invited to review proposals for NSF and NASA.
