Field measurements were collected in seven spatially independent burn scars, within the Yellowknife megafire complex, which had burned between June and August 2014.
New data from NASA's ABoVE field campaign provide estimates of carbon emissions from the 2014 NWT mega-fire complex.

The differenced Normalized Burned Ratio (dNBR) for a burn scar from fires in 2015 within ABoVE grid tile Bh05Bv03. A higher dNBR indicates a higher fire severity.
New data from NASA's ABoVE campaign provides a high-resolution record of differenced Normalized Burned Ratio (dNBR) for fires from 1985-2015.

Three tower sites at Barrow, Alaska: Barrow Environmental Observatory (BEO) tower, Biocomplexity Experiment, South (BES) tower, and the Climate Monitoring and Diagnostics Laboratory (CMDL) tower.
NASA's ABoVE campaign provides year-round CO2, CH4, and meteorology at five sites on Alaska's North Slope.

Plot of the 0.1 degree gridded STILT footprint model output for August 15, 1982 near the receptor location at Barrow, Alaska. This variable provides 24 hours of surface influence representing the response of the receptor to a unit surface emission (ppm/umol m-2 s-1) of CO2 in each grid cell within a small region close to the measurement location. (From the data file foot1982x08x15x06x00x71.3230Nx156.6114Wx00016.nc)
Land surface influence on atmospheric CO2 and CH4 concentrations in Barrow, Alaska was simulated for 12 selected years from 1982 to 2011 as part of the ABoVE campaign.
