To explore research questions beyond those addressed by ARM’s fixed atmospheric observatories in Alaska, Oklahoma, and the Azores, scientists can propose a field campaign to use one of three ARM mobile facilities (AMF) to collect atmospheric and climate data from under-sampled regions around the world.

Each AMF is designed to operate in any environment—from the cold of the Arctic to the heat of the tropics—for campaigns typically lasting about a year. The third ARM Mobile Facility (AMF3) will soon move to the Southeastern United States.
