The North American Portal on Climate Pollutants seeks to make air pollutant emissions inventory data available to users in an intuitive, easy to navigate format. The website contains the following tools and pages:
- Search Tools included in the left-hand sidebar menu allow users to search the available inventories. Users can search the database for information by inventory, place, source category, pollutant, estimation methodology, emission metric, or guidance document.
- Query Pages associated with the search tool selected. These pages contain various sources of information, such as “Quick Links” and drop-down lists of associated variables from which to choose to further refine the search.
- Search Results pages displaying the results of the query. These pages also feature tools for further refining, displaying and exporting search results. Users seeking to access a large dataset may export a CSV spreadsheet of any report, or write their own application programming interface (API) queries to generate unique spreadsheet exports. They may also write queries to export JSON or XML for use in their own applications and reporting programs.
In addition, the North American Portal on Climate Pollutants is built upon an application programming interface (API) that users are encouraged to employ for their own reports and web applications. Users can also access documentation on the API, which is designed to enhance the distribution of air pollutant emissions inventory data by making them available to researchers and application developers in JSON, XML, and CSV formats.
The Data Dictionary enhances the ability to compare inventory data by creating a common framework that may be used for applying semantic tags to the data.
