Abstract Near real-time quantitative precipitation estimates are required for many applications including weather forecasting, flood forecasting, crop management, forest fire prevention, hydropower production, and dam safety. Since April 2011, such a product has been available from Environment and Climate Change Canada for a domain covering all North America. This product, known as the Regional Deterministic Precipitation Analysis, is generated using the Canadian Precipitation Analysis (CaPA) system. Although it was designed for near real-time use, an archive of pre-operational and operational products going back to 2002 is now available and has been used in numerous studies. This paper presents a review of the various scientific publications that have reported either using or evaluating CaPA products. We find that the product is used with success both for scientific studies and operational applications and compares well with other precipitation datasets. We summarize the strengths and weaknesses of the system as reported in the literature. We also provide users with information on how the system works, how it has changed over time, and how the archived and near real-time analyses can be accessed and used. We finally briefly report on recent and upcoming improvements to the product based, in part, on the results of this literature review.

基于加拿大降水分析的十年科学：CaPA 系统概述和文献综述

摘要 许多应用需要近实时的定量降水估计，包括天气预报、洪水预报、作物管理、森林防火、水电生产和大坝安全。自 2011 年 4 月以来，加拿大环境与气候变化部已提供此类产品，用于覆盖整个北美的域。该产品称为区域确定性降水分析，是使用加拿大降水分析 (CaPA) 系统生成的。尽管它是为近乎实时的使用而设计的，但现在可以使用可追溯到 2002 年的预运行和运行产品档案，并已在众多研究中使用。本文回顾了报告使用或评估 CaPA 产品的各种科学出版物。我们发现该产品在科学研究和业务应用中都取得了成功，并且与其他降水数据集进行了很好的比较。我们总结了文献中报告的系统的优点和缺点。我们还向用户提供有关系统如何工作、系统如何随时间变化以及如何访问和使用存档和近乎实时的分析的信息。我们最后简要报告了该产品最近和即将进行的改进，部分基于该文献综述的结果。以及如何访问和使用存档的和近乎实时的分析。我们最后简要报告了该产品最近和即将进行的改进，部分基于该文献综述的结果。以及如何访问和使用存档的和近乎实时的分析。我们最后简要报告了该产品最近和即将进行的改进，部分基于该文献综述的结果。
