Collaborative Research: ICARUS - Index of Chamber Atmospheric Research in the United States

这是一项合作提案，旨在建立一个在线、开放访问、可搜索的美国大气室内数据中央储存库，称为ICARUS(美国室内大气研究索引)。从小室研究中获得的基本数据通常用作大气模型中的经验输入和约束。包括美国国家大气研究中心(NCAR)在内的九家美国主要研究机构参与了这一项目。这一用于存储、共享和使用大气室数据的可持续的基于网络的基础设施将协同促进美国的大气化学研究。该项目的具体目标是(1)提供每个参与研究小组的大气室实验的可搜索的公共索引；(2)将每个参与小组的过去的大气室数据存档在他们的索引室实验下；(3)标准化大气室数据报告格式；(4)为大气室元数据提供统一的模板；以及(5)简化未来的数据提交。ICARUS中包含的数据产品包括：(A)描述挥发性有机化合物(VOCs)的时间分辨分布的气相数据，例如气态碳氢化合物、氧化VOCs、氧化剂(OH、O3、NO3)、NOx、SO2和其他数据；(B)描述二次有机气溶胶(SOA)产率以及光学性质、组成(详细的分子和整体元素比率)和化学官能团的颗粒相数据；(C)支持信息，如相对湿度、温度和光通量；(D)了解数据所需的实验笔记(如反应时间、混合程序、种子颗粒添加等)；和(E)校正燃烧室数据所需的蒸气和颗粒壁沉积速率。在为期3年的项目结束时，数据库将移交给NCAR的数据管理工程团队。

This is a collaborative proposal to build an online, open-access, searchable, central repository for atmospheric chamber data in the United States called ICARUS (Index of Chamber Atmospheric Research in the United States). Fundamental data obtained from chamber studies are routinely used as empirical inputs and constraints in atmospheric models. There are nine major U.S. research institutions participating in this project, including the National Center for Atmospheric Research (NCAR). This sustainable web-based infrastructure for storing, sharing, and using atmospheric chamber data will synergistically facilitate atmospheric chemistry research in the U.S.The specific objectives of the project are to (1) provide a searchable public index of the chamber experiments from each participating research group; (2) archive past chamber data from each participating group under their indexed chamber experiment; (3) standardize chamber data reporting formats; (4) provide a uniform template for chamber metadata; and (5) streamline future data submissions. The data products included in ICARUS are: (A) gas phase data that describes the time-resolved profiles of volatile organic compounds (VOCs) such as gaseous hydrocarbons, oxidized VOCs, oxidants (OH, O3, NO3), NOx, SO2, and other data; (B) particle phase data that describes yields of secondary organic aerosols (SOA) as well as optical properties, composition (detailed molecular and bulk elemental ratios), and chemical functional groups; (C) supporting information such as relative humidity, temperature, and light flux; (D) the experimental notes required to understand the data (such as reaction timing, mixing procedures, seed particle addition, and so on); and (E) vapor and particulate wall deposition rates that are needed to correct chamber data. At the end of the 3-year project, the database will be transitioned to the Data Stewardship Engineering Team at NCAR.
