Chapter 2 - Dataset Information
 
This section provides maps of the towers and data reports.
 
Data Availability Information -
These reports indicate the number of years of data and the number of years of each variable there are in the dataset on a per site basis.
Data Explanations -
These reports provide the datumtype names, units, and calculation methods.
Proposals -
This section of the page provides links to access the data fair use policy and the list of currently accepted synthesis proposals as well as the proposal team support functionality.
Maps and imagery -
The map of the sites is interactive based on Microsoft's Popfly capability.  Initially you should see a broad overview map with each tower marked with a tower colored by vegetation type of the site. The towers on the map mark tower locations that have data in the current fluxnet synthesis effort; the dots mark towers that do not have data in the synthesis set. If you move over an icon marking a site information about the site will appear. To move around on the map, hold down your mouse button over the map and drag the map the direction you want to move.  Double-click on a location in the map to center on that location and zoom in on it.  As you change zoom levels, the imagery shown on the map will change according to the resolution needed. If there are two towers very near each other, you may need to zoom in to be able to differentiate between the towers.
 
The controls for the map are in the upper left corner. To zoom out from the map, click on the magnifying glass with the minus symbol in it. To zoom in without recentering, click on the magnifying glass with the plus symbol in it. The default view of the map is the hybrid of the aerial view and the road view. If you prefer to see a view without the labels and roads, then choose Aerial in the upper left hand controls. To see only the labels and roads, chose Road in the upper left hand controls.
 
NOTE: This map functionality depends on javascript so you will have to have javascript enabled to see the map properly. 
 
Also available in this section is a link to the site imagery allowing views of the site at different zoom levels.  This imagery uses the provided site latitude and longitude and the virtual earth database to generate the images.
 
Site Ancillary and Average Values -
Each of these pages is an excel spreadsheet that can be viewed through the web site.  The data in the spreadsheet is generated from the database. The ancillary data reports provide general information about the sites such as location, vegetation type, climate, years of data, etc. The site curator reports indicate the person who is responsible for collection of flux/met data and the person responsible for collecting flux/met and ancillary data from the sites. Also included is a report which provides the average annual values of the climate data based on the data provided to the fluxnet synthesis effort.

 Network Specific Information -

This section provides network specific access to the L3/L4 data and reports and contains information about networks that have requested this feature. To date this is only AmeriFlux but we are happy to add any others that are interested.

Retired Dataset Versions -

As the dataset evolves and matures, new updated flux/met data and ancillary data is being provided.  The database and web site will always make every attempt to provide the latest information available but since this latest information is potentially in flux, we also provide stable releases of the dataset that will not change.  Every six months, a new stable version of the dataset will be released and frozen.
