This study provide critical measurements on 3-dimensional structure of vegetation, which is important for quantifying the amount of carbon stored in biomass. It promotes the understanding of vegetation response to changing forcing factors such as climate, storm frequency, and management practices, and is directly traceable to missions such as MODIS, MISR, and ICESat-2.During the ECO-3D mission in 2011, the CAR instrument was flown aboard the NASA P-3 and obtained measurements of bidirectional reflectance distribution function (BRDF) over forests ranging from Boreal to tropical wetlands covering sites from Quebec to Southern Florida.This data set consists of observations made with the CAR instrument and includes values for bidirectional reflectance factor at varying spectral bands.
