A spectrophotometer was used to scan the canopy vegetation at four sites near Imnavait Creek each year from 2008 - 2010 by Toolik Lake LTER, Alaska. Reflectance spectra from 310-1130 nm are presented here with information relating the date and site of the scan.
A spectrophotometer was used to scan the canopy vegetation at four sites along Imnavait Creek in the Kuparuk Watershed near Toolik Lake LTER, Alaska. The resulting reflectance spectra were used to calculate average vegetation indices for each site and collection day.
Vegetation indices calculated from reflectance spectra collected at Arctic LTER plots at Toolik Lake, Alaska during the 2007-2016 growing seasons. Canopy reflectance was measured using a dual channel spectrophotometer (Unispec DC, PP Systems, Amesbury, Massachusetts, USA). Spectral indices were calculated for NDVI (MODIS, EVI (MODIS), EVI2 (MODIS), PRI (550 Reference), PRI (570 Ref), WBI and Chl Index
