What is the difference between http://www.fluxnet.ornl.gov/fluxnet/ and the http://www.fluxdata.org/ ?

FLUXNET is a NASA-funded component of the ORNL DAAC. IT provides summary information about flux towers and links to eddy covariance data at regional networks.

Fluxnet.org is a Microsoft-funded activity to compile the 30-minute flux data in a relational database (data cube) in support of analyses conducted as part of the La Thuile over Workshop held in January 2007.
