This session will explore the emerging opportunities to leverage new data sources to understand and assess human behavior in response to forecasts and warnings. The panelists will explore potential big data sources and how they could complement longer term data and research on socio-economic trends that are crucial to better understand human behavior in response to weather and climate hazards. The panel will also address the associated policy, budget, training and technical opportunities and challenges inherent in realizing a robust socio-economic underpinning for the weather enterprise.
