Flux Anomaly Time Series

Time series of the exchange anomalies calculated with CarbonTracker Europe aggregated over larger areas of the globe. The title reflects areas defined in the TransCom project and can be found on this map. The red line is the final result from CarbonTracker with a 3-month boxcar average applied to remove variations on the shorter timescales. The yellow line is the a-priori estimated anomaly. All units are PgC/yr. This figure includes biological and fire fluxes, no fossil fuels.

The table summarizes average anomalies of the data displayed in the figure. Negative values denote an increase in uptake (or reduction of carbon release) and positive values denote reductions in uptake (or increases in release). The total flux is the sum of the components in the table.

The annual anomalies for all years in the table are shown here relative to the long-term mean. The figure illustrates how years with higher (negative) or lower than average (positive) uptake have progressed, and in which month of the year the anomalies have increased or decreased. The average seasonal cycle is subtracted from all lines and thus lies on the 0.0 line in this figure.
