Box 757000, Fairbanks, AK 99775-7000. http://www.geobotany.uaf.edu FUNDING: LAII/ATLAS - OPP 9908829 DATASET OVERVIEW DATA DESCRIPTION: This dataset contains leaf area index (LAI) measurements taken at peak biomass at the Barrow site on the Arctic Slope of Alaska, in 1999. INSTRUMENT DESCRIPTION: LAI data obtained using the LI-COR LAI-2000 Plant Canopy Analyzer. See this website for details- http://env.licor.com/Products/AreaMeters/lai2000/2000.htm DATA COLLECTION AND PROCESSING: LAI measurements were obtained by taking readings from the LAI meter (one above the canopy, and one below) every meter for the 50 meters along each transect. Four LAI measurements were also taken within each 20 x 50 cm (0.1m2) area biomass harvest area, or "clip", prior to harvesting. For biomass data see the _biomass.xls file for this site. LAI instrumentation used was the LI-COR LAI-2000 Plant Canopy Analyzer. DATA FORMAT: File Name = barrow_lai_msmts_1999.xls (Excel format). It is a numeric data file. File size is 12K. This final version of the data file was submitted to JOSS 03/29/2002. For more data related to these sites, see: http://www.geobotany.uaf.edu
