Figure 1. Residuals (simulated - observed) for aircraft profiles at the specified site, shown as a function of date and sample elevation. Units are μmol mol-1 of CO2. Each dot represents one observation. Vertical black line at March 13, 2021 marks the beginning of CT-NRT.v2024-1 period. Prior to this date results from CT2022 are plotted. Aircraft data are not assimilated in CarbonTracker.




Figure 2. Measured CO2 for aircraft profiles at the specified site, shown as a function of date and sample elevation. Units are mol mol-1. Each dot represents one observation. Vertical black line at March 13, 2021 marks the beginning of CT-NRT.v2024-1 period. Prior to this date results from CT2022 are plotted.

Figure 3. Statistical summary of residuals (simulated - observed) for aircraft profiles at the specified site, shown as a function of season and elevation. Units are μmol mol-1 of CO2. The shaded area spans the 25th to 75th quantile range, with the median residuals given by the red line. These statistics are generated using all observations falling within the specified months and within each 1000m layer. Aircraft data are not assimilated in CarbonTracker.
