The NACP data set “Woody Vegetation Characteristics of 1,039 Sites across the North Slope, Alaska” (http://dx.doi.org/10.3334/ORNLDAAC/1270) contains statistics on shrub canopies (shrubs > 0.5 m in height) in 250 × 250 m sites across the North Slope of Alaska, ca 2010. It provides the results of (1) field measurements of woody vegetation (shrubs) at 26 diverse sites across the North Slope of Alaska during 2010 and 2011, (2) field-based statistical estimates of site shrub structural characteristics, (3) high-resolution panchromatic satellite imagery-based estimates of the field site shrub characteristics using the Canopy Analysis with Panchromatic Imagery (CANAPI) model, and (4) adjusted CANAPI estimates of shrub characteristics at 1,013 selected sites widely distributed across the North Slope. The data set was constructed in several stages: aerial survey; field inventory; interpretation of high resolution QuickBird and GeoEye panchromatic imagery made available by National Geospatial-Intelligence Agency (NGA) Commercial Archive Data; and collation of results. The two field campaigns on the North Slope took place during 24 July - 12 August 2010 and 20 July - 9 August 2011 at the peak of the growing season. The 2010 campaign included sites accessible via the Chandler and Colville Rivers, from the Brooks Range to the Arctic Coastal Plain, while the 2011 campaign surveyed 12 sites along the Dalton Highway from the Brooks Range to the Arctic Coast. This data set should prove useful to researchers in NASA's upcoming Arctic-Boreal Vulnerability Experiment who need access to validation data for assessing medium (10-30 m) and moderate resolution (>250 m) Earth Observation products.
