Arctic-CAP flights consisted of vertical profile maneuvers from near the surface to 6 km altitude around the ABoVE domain each month. Profiles were flown at each of the 25 locations listed across the top of this figure.
Atmospheric gas concentrations collected during the Arctic Carbon Aircraft Profile (Arctic-CAP) campaigns are now available.

Daily mean shortwave blue sky albedo for February 28, 2000. Blue sky refers to albedo calculated under real-world conditions with a combination of both diffuse and direct lighting based on atmospheric and view-geometry conditions.
Daily “blue sky” shortwave albedo data were derived from the MODIS bi-directional reflectance distribution function.

Peak greenness derived from the Normalized Difference Vegetation Index (NDVI) for the year 2010 in the ABoVE grid cell Bh07v07.
Maps of annual seasonality and greenness are now available from the Arctic-Boreal Vulnerability Experiment.

Annual expansion of a thaw slump on the East Fork Chandalar River near the community of Venetie, Alaska, from 2008 through 2017. The erosion time series was created by digitizing data from ESRI base maps and Landsat 5, 7, and 8 images. The eroded area appears to be growing steadily, mostly to the east, with apparent limitation on growth to the north and south.
A time series of Landsat-derived maps shows the expansion of a thaw slump in Alaska.
