Welcome to the web pages of the Global Tropical Moored Buoy Array program. Our goal is to design, develop and sustain moored buoy observing systems in the tropics for climate research and forecasting through collaborative multi-national efforts.  In these pages you will find real-time and historical data from tropical Pacific, Atlantic, and Indian Oceans, as well as data displays and information about climate variations like El Niño and La Niña. We hope you find these pages useful and welcome suggestions on how we can improve them.
