Federal Land Manager Environmental Database (FED)
This website provides access to an extensive database of environmental data and an integrated suite of online tools and resources to help Federal Land Managers assess and analyze the air quality and visibility in Federally-protected lands such as National Parks, National Forests, and Wilderness Areas.
 |
AQRV Summaries
View graphical summaries and reports of the status and trends of air-quality-related values (AQRVs) and other metrics that have been chosen by Federal Land Managers (FLMs) for assessing air quality in protected federal areas.
|
 |
Webcams and Photographs
See live video from webcams at select rural and urban vistas, and examine sequences of photographs from selected monitoring sites that demonstrate the range of visual conditions at each site over time.
|
 |
Data Visualization and Exploration
Use a variety of interactive tools and applications to visualize, explore, filter, and download raw and aggregated air quality data and relevant metadata from the integrated database in a variety of customizable formats.
|
 |
Metadata and Reference
Find and explore detailed metadata about datasets, monitoring sites, parameters, sampling and analysis protocols, processing methods, data flags, and other aspects of the air quality data in the integerated database.

 |
Database Query Wizard
The query wizard allows you to selectively download data and metadata from the FED integrated database by specifying datasets, monitoring sites, parameters, date ranges, data quality flags, and other criteria. You can request data in variety of output formats.

The new Data and Metadata File Explorer tool is availableYou can use this new tool to access the original data and metadata files that have been obtained from various providers and data sources for inclusion in the integrated database.A new photo banner has been addedA new photographic banner has been added that features panoramic photos from many of our national parks and wilderness areas. Click on the photograph above when you're ready to see the next one. Soon, each photo will be linked to the data from that park.

The Oct-Dec 2009 IMPROVE data is availableThe October through December 2009 IMPROVE data has been imported and the 2009 RHR metrics have been generated. You can browse and download the data using the Query Wizard.Many new datasets have been addedMany new datasets that were previously unavailable from FED have been added recently, including CASTNet Ozone data, CASTNet Multi-Layer Model data, EPA Carbon Monoxide (CO) data, and EPA Sulfur Dioxide (SO2) data. See the Query Wizard for details.

Featured Term
Mie scattering The attenuation of light in the atmosphere by scattering due to particles of a size comparable to the wavelength of the incident light. This is the phenomenon largely responsible for the reduction of atmospheric visibility. Visible solar radiation falls into the range from 0.4 to 0.8 µm, roughly with a maximum intensity around 0.52 µm.
