The 4 th meeting of the ABoVE Science Team, held in Seattle 23-26 January 2018, was by all accounts a great success. Over 150 attendees from NASA, other federal, state, and Canadian agencies, and US and Canadian universities assessed the latest in ABoVE science via a series of invited plenary talks, partner presentations, posters sessions and breakout discussions. Some participants who registered for the meeting were unable to attend due to the government shutdown on the day before the meeting, but NASA headquarters participants (including Hank Margolis, Eric Kasischke and Ken Jucks) were able to make it by the second day of the meeting. Invitational travel helped a number of students, postdoctoral researchers and collaborators to attend, which ultimately included 20 graduate students and 17 postdocs. Many of the 116 poster presentations were led by students and postdocs, and the daily afternoon poster sessions provided a lively and bustling interaction among all participants. A number of attendees mentioned it had the high quality of the much bigger AGU meetings, but intensely focused on common research interests within the ABoVE domain.
