BOREAS RSS-20 POLDER HELICOPTER-MOUNTED MEASUREMENTS OF SURFACE BRDF
Get Data

Summary:

This data set contains measurements of surface BRDF made by the POLDER instrument over several sites (pine, spruce, fen) of the BOREAS study areas during 1994. Single-point BRDF values were acquired from NASA's WFF helicopter. A related data set collected from the C-130 platform is available as is POLDER imagery acquired from the C-130.

A guide document which includes more information about this data set can be found at http://daac.ornl.gov/boreas/RSS/rs20helo/comp/RSS20_POLDER_Helo.txt.

ORNL DAAC maintains information on the entire BOREAS Project.
