The 5th meeting of the ABoVE Science Team (ASTM5) was held in San Diego, CA from May 20th-23rd 2019. There were some 125 attendees from NASA and other US federal agencies, Alaska, and a variety of Canadian federal agencies, a non-profit conservation organization, and indigenous groups. There were also many attendees from US, Canadian and European universities. The overarching goal of the meeting was to collectively assess the latest in ABoVE science via a series of invited plenary talks, partner presentations, posters sessions, and lively breakout discussions. Invitational travel helped a number of students, postdoctoral researchers and collaborators attend. Many of the 84 poster presentations were led by students and postdocs, and the afternoon poster sessions provided vibrant and productive interactions among meeting participants.
