Variability of boreal forest reflectances as measured from a helicopter platform

Helicopter and surface‐based radiometric measurements of forested sites acquired during the Boreal Ecosystem‐Atmosphere Study (BOREAS) were analyzed to assess reflectance variability and to address the relationships of reflectances and vegetation indices (VIs) with overstory leaf area index (LAI). Statistical measures of central tendency and linear regression analysis, including a multivariate regression which introduced the effects of …
