There is a wealth of data on air pollution within several users' reach, including modelled concentrations and depositions as well as observations from air quality stations. However, data integration to perceive spatial and temporal trends at the national level is a complex undertaking. The difficulties are mainly related to the data sources (many files with a lot of information and in different formats). In addition, the processing of this data is time-consuming and impractical when the time period under analysis increases. Furthermore,the processing of spatial-temporal data requires the use of multiple specific tools, such as geographic information systems software and statistical, which are not readily accessible to non-specialised users. The proposed solution is to develop libraries that are responsible for aggregating different types of data related with pollution. In addition to allowing the integration of different data, the libraries are also the basis for developing web applications. The libraries allow the collection of data made available by the Portuguese Environment Agency (APA) and official modelling results for Europe. The applications developed will extend the libraries to allow data processing and representation through Dashboards. These Dashboards provide access to non-specialised users, namely regarding the trends of pollutants in each region. The implemented libraries allow the development of projects that would need access to the same data sources. These Dashboards allow for simplified access to data and for studies that have so far been beyond the reach of researchers.

GAPS：用于空气污染研究的地理数据门户

在多个用户可及的范围内，有大量的空气污染数据，包括模拟的浓度和沉积以及从空气质量站获得的观测数据。但是，为了在国家一级了解时空趋势而进行数据集成是一项复杂的工作。困难主要与数据源有关（许多信息很多且格式不同的文件）。另外，当所分析的时间段增加时，该数据的处理既费时又不切实际。此外，时空数据的处理需要使用多个特定工具，例如地理信息系统软件和统计信息，这对于非专业用户来说是不容易获得的。提出的解决方案是开发负责汇总与污染有关的不同类型数据的库。除了允许集成不同的数据外，这些库还是开发Web应用程序的基础。这些库允许收集葡萄牙环境局（APA）提供的数据以及欧洲的官方建模结果。开发的应用程序将扩展库，以允许通过仪表板进行数据处理和表示。这些仪表板为非专业用户提供访问权限，即有关每个区域污染物趋势的信息。已实现的库允许开发需要访问相同数据源的项目。
