Spectral Reflectance Measurements NIMS grid Atqasuk, Alaska 2011
Spectral measurements were taken at each meter of the Networked Info-mechanical Systems (NIMS) grid in Atqasuk, Alaska during the summer of 2011. The NIMS grid is situated about 50 meters to the south of the International Tundra Experiment (ITEX) dry sites. Measurements were taken from the edge of e...
