Spectral reflectance measurements were taken at each meter of the NIMS grid in Imnavait, Alaska during the summer of 2012. The data was collected using a Unispec DC spectrometer with fiber optics, mounted on a tripod at a height of 1.62 meters, resulting in a calculated footprint of 50-60 cm per scan. The dataset was last updated on July 30, 2012.
Spectral reflectance measurements were taken at each meter of the NIMS grid in Barrow, Alaska during the summer of 2012. The data was collected by SCIOPS using a Unispec DC spectrometer with a specific sensor angle and footprint. Measurements were taken from the edge of white boards aimed at plots located about 200 meters northeast of the ITEX dry sites.
