General Description:
The Tropical Western Pacific (TWP) locale was established in 1996 as the second ARM Climate Research Facility site. Operated by the Tropical Western Pacific Office (TWPO) at Los Alamos National Laboratory, the TWP site consists of three climate research facilities: the Manus facility on Los Negros Island in Manus, Papua New Guinea (established in 1996); the Nauru facility on Nauru Island, Republic of Nauru (1998); and the Darwin facility in Darwin, Northern Territory, Australia (2002).
The facility is situated adjacent to the Australian Bureau of Meteorology's (BOM) Meteorological Office near Darwin International Airport.
