1 Technical Cooperation in Development of the South Asian Regional Reanalysis (SARR) to advance Understanding, Modeling, and Prediction of Monsoon Hydroclimate Variability and Change between the National Oceanic and Atmospheric Administration (NOAA) Department of Commerce of the United States of America and the Ministry of Earth Sciences (MoES) of the Government of ndia This text constitutes an mplementing Arrangement under Article V of the Memorandum of Understanding between the Government of ndia's Ministry of Earth Sciences (MoES) and the Government of the United States of America's National Oceanic and Atmospheric Administration (NOAA) on Technical Cooperation in Earth Observations and Earth Sciences.. Purpose This mplementing Arrangement provides a framework for collaboration between the Ministry of Earth Sciences (MoES) of ndia and the National Oceanic and Atmospheric Administration (NOAA) Department of Commerce of the United States of America (hereinafter, "the Parties") concerning the Development of the South Asian Regional Reanalysis (SARR) to advance Understanding, Modeling, and Prediction of Monsoon Hydroclimate Variability and Change. While intended to serve as a vehicle for continuing collaboration, it is being implemented for an initial five-year period. 11. Objectives A retrospective analysis (reanalysis) of circulation and thermodynamic fields over South Asia will be developed to advance characterization, understanding, modeling, and prediction of monsoon climate variability and change over this vastly populated subcontinent of complex orography, land-surface types, and land-ocean boundaries. nterest in regional hydroclimate (precipitation, surface temperature, soil moisture, stream flow, drought indices, etc.) is intense and growing, given the direct societal impacts. Through additional assimilation of precipitation, radiance, and aerosol observations in numerical weather prediction models, the South Asian Regional Reanalysis project will generate refined description of the regional hydroclimate state; a description unattainable from canonical assimilation of circulation and temperature data as model forecasts of precipitation

2 remain inaccurite. The SARR project will thus provide an atmosphere-land-surface state description where consistency between circulation and hydroclimate components is assured. The South Asian Regional Reanalysis project will exploit the high spatio-temporal resolution of satellite observations; generate unique synthesis of conventional and remotely sensed data using state-of-the-art atmosphere/land-surface models while being mindful of regional water and energy budgets; develop comprehensive summer and winter monsoon phenomenologies from closer interaction of the modeling and observational communities; provide a framework for diagnosing the influence of regional anthropogenic aerosols/pollutants on circulation and hydroclimate; permit a more rigorous analysis of water resource management and agricultural practices; and above all, forge stronger links between climate programs of South Asian countries Areas of k ooperative Activity The project is motivated by intersections of US-NOAA and ndia-moes interests in weather and climate prediction over the South Asian subcontinent and the ndian Ocean basin. n the following, 'US' and 'ND' mark key interests of the two countries. Societal mpact: Provide consistent description of hydroclimate (precipitation, soil moisture, stream flow, drought indices, surface temperature) to the agricultural economies of the region. (ND) PCC Relevance: Facilitate climate-change detection and attribution over Asia - home of two large energy-hungry economies. Circulation-hydroclimate consistent records are presently unavailable for a discriminating analysis of regional climate change. (ND, US) Regional Science: Advance understanding of the dynamic and thermodynamic mechanisms that mediate localhemote forcing (aerosols, El Nino Southern Oscillation, North Atlantic Oscillation, etc.) and the monsoon response. (ND, US) Global Teleconnections: Develop refined description of the influence of the South Asian monsoon and ndian Ocean on evolution of the El Nino Southern Oscillation and the PacificNorth American climate. (US) Observation-Model Bridge: Forge strong connections between ndia's observational and modeling scientists, leading to improved nowcasting and forecasting of regional weather and climate. (ND) Specific SARR Goals The goals of the collaborative project are: Refine methods for assimilation of precipitation and radiances with the goal of reducing the water and energy budget imbalances during the assimilation procedure

3 Conduct a kyear pilot-phase reanalysis for the period , to test and optimize data stream organization and the geographic domain and assimilating model choices. The short, modem period reanalysis will be evaluated fiom intercomparisons with satellite observations (e.g., TRMM) and state-of-the-art global analysis (e.g., ERA40); and the assimilating technique refined as necessary. Develop high-resolution SST analysis for the ndian ocean from satellite and in-situ observations, including moorings, drifters and Argo floats Design techniques for assimilation of aerosols mprove state estimation of the Northem ndian Ocean from refined surface circulation and heat-flux estimates produced by the regional atmospheric reanalysis Generate a dynamics-thermodynamics consistent, high spatio-temporal resolution (S30 Km, 53 hours) climate data set from retrospective analysis of in-situ and remotely sensed ocean-atmosphere observations for the period over the South Asian Monsoon land-ocean region.
