Query pages allow users to refine their queries when exploring the North American Portal on Climate Pollutants, and are accessed by clicking on the Search tools in the left-hand sidebar menu. These pages display links and summary information related to the selected search tool, as well as drop-down lists with options to refine the query.
For example, the Query page associated with an Emission Metric search will contain a drop-down list allowing the user to select variables that will place the emission metrics in context—i.e., by Inventory, Year, Place, Pollutant, Source Category, or Estimation Methodology, based on whether data exist to populate the report.
Similarly, the Query page for a Source Category search will contain a drop-down list of variables associated with air pollutant emission source categories—i.e., Guidance Documents, Inventories, Pollutants, and Estimation Methodologies, based on whether data exist to populate the report.
Please see the Search Results documentation pages to learn about using the tools included on search result pages.
