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

这是一项合作提案，旨在为美国的大气室数据建立一个在线、开放访问、可搜索的中央储存库，称为ICARUS（美国大气室研究索引）。 从电离室研究中获得的基本数据通常用作大气模型的经验输入和约束。美国有九个主要研究机构参与了这个项目，其中包括国家大气研究中心（NCAR）。 该项目的具体目标是（1）提供每个参与研究小组的室实验的可搜索公共索引;（2）将每个参与小组过去的室数据存档在其索引室实验下;（3）将每个参与小组的室数据存档在其索引室实验下;（4）将每个参与小组的室数据存档在其索引室实验下;（5）将每个参与小组的室数据存档在其索引室实验下。（3）标准化商会数据报告格式;（4）为商会元数据提供统一模板;（5）简化今后的数据提交。 ICARUS中包含的数据产品有：（A）描述挥发性有机化合物（VOC）（如气态烃、氧化VOC、氧化剂）的时间分辨剖面的气相数据（OH、O3、NO3）、NOx、SO2等数据;（B）描述二次有机气溶胶（SOA）的产率以及光学性质、组成的颗粒相数据（详细的分子和体积元素比）和化学官能团;（C）支持信息，如相对湿度，温度和光通量;（D）理解数据所需的实验笔记（例如反应时间、混合程序、种子粒子添加等）;以及（E）校正腔室数据所需的蒸气和微粒壁沉积速率。 在3年项目结束时，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.
