Air Quality Related Values (AQRV) - Express Tools

An Air Quality Related Value (AQRV) is a resource, as identified by the Federal Land Manager, for one or more federal areas that may be adversely affected by a change in air quality. The resource may include visibility or a specific scenic, cultural, physical, biological, ecological, or recreational resource identified by the Federal Land Manager for a particular area. The tools below provide access to a variety of graphical and tabular products for assessing the impacts to air quality related values in Federal Class 1 Areas from haze, ozone, and wet/dry deposition.
These express tools provide the quickest and most direct way to generate data products. They are designed with a very basic user interface (UI) in order to be simple and straightforward to use. Each numbered row/item below represents a single tool that produces a unique report. Make your selections from the dropdown menus and then click the Submit button to generate your results. You can mouse-over the hyperlinked tool names in the "Product" column in order to get a brief description and preview of the tool's output. Because new tools will be added over time and old tools periodically retired, you should not depend upon the sequential numbering of the tools in order to reference them. If you wish to obtain or share a unique reference to an individual tool, you can click on the tool's sequence number in the "#" column for a popup window that displays the tool's unique ID and Code, values that will remain unchanged even if the tool's sequence number changes. To save or share a link to a specific instance of a tool's output report, first make your selections from the tool's menus and then click on the link icon in the "URL" column to obtain the full URL to the associated report, which is considered a "permalink" that can be used as an embedded hyperlink in documents, web pages, and papers.
