Image Media
Caption
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)
Body
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.
