Spectral Reflectance Measurements ARCSS grid Atqasuk, Alaska 2010
Spectral measurements were taken on a 30 plot subset within the Arctic System Science (ARCSS) grid in Atqasuk, Alaska during the summer of 2010. Spectral measurements were taken from the north eastern most corner of each plot. The subset is located from E2-E6 & J2-J6 with the 1 km^2 ARCSS grid....
