Extended Data Fig. 7: Difference in airborne EC mean flux and SAR mean flux as a function of lake size.

Circles represent individual lakes in the Barrow Peninsula region (a) and Atqasuk region (b). Difference values greater than zero (black line) indicate how much higher the airborne EC estimated flux for each lake was compared to the June/July SAR-estimated flux. Difference values lower than zero indicate SAR-based estimates higher than airborne EC-based estimates. Note different scale in x-axis for each region.
