RAPID: Coordinated Rainfall Analysis of Hurricane Harvey

飓风哈维的登陆和缓慢移动造成了美国有史以来最罕见的降水事件之一。这一快速反应奖将创造一个研究质量的降雨分析产品，水文学家、气象学家和工程师可以使用该产品来研究洪水和极端降雨事件。传统的降雨分析产品受到基础数据的潜在误差以及地面测量与气象雷达估算的降雨混合方式的差异的限制。该项目的研究人员将收集有关雨量计的数据，并测试各种分析技术，以提供具有高空间和时间分辨率和可量化的不确定性估计的产品。该项目的影响将是帮助改进城市洪水的模拟，并更好地了解极端降水事件。当地高中生将组队为该项目收集数据，并向他们介绍科学研究活动。研究小组将创建一套基本的降雨数据、元数据和分析，用于极端降水事件的大气、水文和工程研究。项目的主要目标之一是创建用于降雨分析的信息的一致性和准确性。研究小组将与其他利益相关者合作，建立元数据需求和标准，然后从网络运营商那里收集元数据。还将评估不同的降雨分析技术以及分析对技术和参数选择的敏感性。该项目的一个结果将是为研究界提供分析和不确定性量化。该研究项目的其他方面将是将哈维的降雨置于历史背景中，并建立一个用于比较雨量计网络性能的数据集。

The landfall and slow movement of Hurricane Harvey created one of the most exceptional precipitation events on record in the United States. This rapid response award will result in the creation of a research-quality rainfall analysis product that can be used by hydrologists, meteorologists, and engineers to study flooding and extreme rainfall events. Traditional rainfall analysis products are limited by potential errors in the underlying data and differences in how ground-based measurements are mixed with weather radar estimates of rainfall. The researchers in this project will collect data about the rain gauges and test the various analysis techniques to provide a product that has high spatial and temporal resolution and quantifiable uncertainty estimates. The impact of the project will be to help improve simulations of urban flooding and to better understand extreme precipitation events. Local high school students will work on teams to collect data for the project, introducing them to scientific research activities.The research team will create a foundational set of rainfall data, metadata, and analyses for use in atmospheric, hydrologic and engineering studies of extreme precipitation events. One of the main project goals is to create a level of consistency and accuracy of the information that goes into the rainfall analyses. The research team will work with other stakeholders to establish metadata needs and standards and then collect the metadata from the network operators. Different rainfall analysis techniques and the sensitivity of the analyses to technique and parameter choices will also be assessed. One result of the project will be to provide analyses and uncertainty quantification to the research community. Other aspects of the research project will be to place Harvey's rainfall into historical context and to establish a dataset for comparison of rain gauge network performance.
