Spectral Reflectance Measurements ARCSS grid Barrow, Alaska 2012
Spectral measurements were taken on a 30 plot subset within the Arctic System Science (ARCSS) grid in Barrow, Alaska during the summer of 2012. Spectral measurements were taken from the north eastern most corner of each plot. The subset is located from D2-D7 & H2-H7 within the 1 km^2 ARCSS grid....
