World Data Center for Aerosols

The World Data Centre for Aerosols (WDCA) is the data repository and archive for microphysical, optical, and chemical properties of atmospheric aerosol of the World Meteorological Organisation's (WMO) Global Atmosphere Watch (GAW) programme. The goal of the Global Atmosphere Watch (GAW) programme is to ensure long-term measurements in order to detect trends in global distributions of chemical constituents in air and the reasons for them. With respect to aerosols, the objective of GAW is to determine the spatio-temporal distribution of aerosol properties related to climate forcing and air quality on multi-decadal time scales and on regional, hemispheric and global spatial scales. You can find data in EBAS: https://ebas-data.nilu.no/Default.aspx. The data reported to WDCA are identified in the database by the associations GAW-WDCA (for regularly, annually reported data) and GAW-WDCA_NRT (for data reported in near-real-time).

世界气溶胶数据中心（WDCA）是世界气象组织（WMO）全球大气观测（GAW）计划中大气气溶胶的微物理、光学和化学特性的数据存储库和档案。全球大气观测（GAW）计划的目标是确保长期测量，以便检测空气中化学成分在全球分布中的趋势及其原因。在气溶胶方面，GAW的目标是在多十年时间尺度上，以及区域、半球和全球空间尺度上，确定与气候强迫和空气质量相关的气溶胶特性的时空分布。您可以在EBAS（https://ebas-data.nilu.no/Default.aspx）中找到数据。报告给WDCA的数据在数据库中通过GAW-WDCA（用于定期、年度报告的数据）和GAW-WDCA_NRT（用于近实时报告的数据）的关联进行标识。
