HFM_01P2: Discrete Sampling Package, aircraft measurements from Harvard Forest, Massachusetts, United States located at 42.5378N, 72.1714W and 340.00 masl. Measurements are made by NOAA Earth System Research Laboratory (ESRL).
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. Aircraft data are not assimilated in CarbonTracker.



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.
