A decision framework is developed for quantifying the economic value of information (VOI) from the Gravity Recovery and Climate Experiment (GRACE) satellite mission for drought monitoring, with a focus on the potential contributions of groundwater storage and soil moisture measurements from the GRACE Data Assimilation (GRACE-DA) System. The study consists of: (a) the development of a conceptual framework to evaluate the socioeconomic value of GRACE-DA as a contributing source of information to drought monitoring; (b) structured listening sessions to understand the needs of stakeholders who are affected by drought monitoring; (c) econometric analysis based on the conceptual framework that characterizes the contribution of GRACE-DA to the US Drought Monitor (USDM) in capturing the effects of drought on the agricultural sector; and (d) a demonstration of how the improved characterization of drought conditions may influence decisions made in a real-world drought disaster assistance program. Results show that GRACE-DA has the potential to lower the uncertainty associated with our understanding of drought, and that this improved understanding has the potential to change policy decisions that lead to tangible societal benefits.

遥感信息的价值：以 GRACE 增强的干旱强度指数为例。

开发了一个决策框架，用于量化来自重力恢复和气候实验 (GRACE) 卫星任务的干旱监测信息的经济价值 (VOI)，重点关注来自 GRACE 数据同化的地下水储存和土壤水分测量的潜在贡献(GRACE-DA) 系统。该研究包括： (a) 开发一个概念框架，以评估 GRACE-DA 作为干旱监测信息来源的社会经济价值；(b) 结构化的聆听会议，以了解受干旱监测影响的利益攸关方的需求；(c) 基于 GRACE-DA 对美国干旱监测 (USDM) 在捕捉干旱对农业部门影响方面的贡献的概念框架进行计量经济分析；(d) 展示改进的干旱条件表征如何影响现实世界干旱灾害援助计划中的决策。结果表明，GRACE-DA 有可能降低与我们对干旱的理解相关的不确定性，并且这种改进的理解有可能改变政策决策，从而带来切实的社会效益。
