TPOS is a multinational observing system designed to measure the subsurface and surface ocean and the atmosphere spanning the tropical Pacific from approximately 10°S to 10°N. Many agencies and institutions contribute to and operate elements of this observing system. TPOS seeks to accelerate advances in technology, understand and predict tropical Pacific variability, and inform policymakers and benefit society.
The Tropical Pacific Observing System (TPOS) is centered in the tropical band of the Pacific Ocean from approximate latitudes of 10°S to 10°N. Check out the in situ and satellite components of the observing system.
Observing the ocean and atmosphere in the tropical Pacific is essential for local and global communities and their economies as it provides key insights into ocean, climate and weather variability and prediction, regionally and globally.
From 2014-2020 the TPOS 2020 Project evaluated the observing system to identify gaps and needs in order to rejuvenate and revamp the system. As the sun sets on that project, we turn our focus toward implementing these recommendations. An archive of the TPOS 2020 Project has been retained on this site.
