Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA): Rationale, Design, First Results, Status & Plans Mike McPhaden NOAA/PMEL Seattle, Washington, USA Fifth Capacity Building Workshop Bali, Indonesia 9 October 2009
Rationale and Design Fifth Capacity Building Workshop Bali, Indonesia 9 October 2009
The Monsoons One third of the world’s population depends on monsoon rainfall
Indian Ocean Science Drivers Seasonal monsoons Severe weather events & cyclones Intraseasonal (30-60 day) Madden Julian Oscillation (affects ENSO, US weather, hurricanes) Interannual variations: the Indian Ocean Dipole Decadal variability and warming trends (affect NAO & North American temperature and precipitation) Ocean circulation & biogeochemistry Indian Ocean is the most poorly sampled region of the tropics Nargis MJO Trends Indian Ocean Dipole

RAMA RAMA: Ancient king of India and hero of the epic “Ramayana”.
ATLAS Surface Moorings Rapid sampling in time to resolve rather than alias high frequencies Multi-variate (ocean, atmosphere, biogeochemical) Fixed grid array so time and space are not mixed Real-time data transmission (Service Argos & Global Telecommunications System) ATLAS

Soc., 90, “A new moored buoy array in the historically data sparse Indian Ocean provides measurements to advance monsoon research and forecasting.”
RAMA: Present Status 52% of sites occupied at present (24 of 46) Resource Formula: NOAA provides most equipment Regional partners provide ship time ORV Sagar Kanya deploys ATLAS mooring

Planned Biogeochemical Measurements: A SIBER-RAMA Initiative Monthly Seawifs Chl-a Concentrations (Solid Dots are RAMA Flux Reference Sites) SIBER=Sustained Indian Ocean Biogeochemical and Ecosystem Research Program Objectives: A)To provide data for defining biogeochemical variability in key regions of the Indian Ocean and for understanding the physical, biological and chemical processes that govern it; B)To provide data for developing models of ocean-atmosphere- biosphere interactions; C)To provide baseline data for assessing the impacts of climate change on ocean uptake of CO 2 and primary productivity in the ocean. Key Measurements: CO 2, pH, Fluorescence, Particle Backscatter, O 2 Target Locations: Arabian Sea, Bay of Bengal, Equator, Seychelles-Chagos Thermocline Ridge

International Cooperation and Capacity Building Formal bilateral agreements: USA (NOAA) and Indonesia (DKP and BPPT)--signed in May 2009 USA (NOAA) and India (MoES)--signed in Sept 2008 USA (NOAA) and Japan (JAMSTEC)--signed in June 2008 China (SOA) and Indonesia (DKP)--signed in 2007 ASCLME (9 East African countries)--planned in 2009 DART/RAMA cruise RV Baruna Jaya III Sept 2007 IndOOS Resource Forum
Established by IOGOOS and Advised by CLIVAR/GOOS Indian Ocean Panel Terms of Reference: To review the requirements for the implementation of IndOOS; To facilitate and coordinate resources that may be applied to the system, especially ship time for RAMA; To encourage scientific and technological initiatives in the participating countries to meet the objectives of IndOOS; To report on its activities to the Heads of the institutions providing resources.
Sustainability Requires Provision of Climate Products and Services to Society Users (Ocean-Atmos-Land-Cryosphere) Feedback & Analyses
