Step1: Select the station

The station can be selected either using the drop down menu or by locating it on the map in the center of the page.

Step 2: Select the year

The drop down menu lists those years for which simulation results are available. In case observations are available for comparison, this is indicated in the drop down list as well.

After the selection of station and year the footprints and CO2 time series will be loaded.

Step 3: Select the CO2 components

By default the STILT-simulated CO2 concentration time series (blue line) is shown and - if available - observed CO2 (black line) is included as well. Values correspond to the left hand side (primary) y-axis.

In the model simulations the contributions from different fluxes are separated:

  • Contributions from natural fluxes co2.bio, split up into uptake of CO2 by photosynthesis co2.bio.gee and release of CO2 by respiration co2.bio.resp.
  • Contributions from anthropogenic emissions, split into:
    • fuel-type specific contributions from burning of coal, oil, gas, biofuel, and waste (co2.fuel.coal, co2.fuel.oil, co2.fuel.gas, co2.fuel.bio, co2.fuel.waste) and cement production (co2.cement)
    • or emissions from different source categories: energy production, industrial processes, transportation, residential heating, and other processes (co2.energy, co2.industry, co2.transport, co2.residential, co2.other_categories).
  • Contributions from sources and sinks outside the model domain co2.background


Note the following relations between the components:

co2.stilt = co2.bio + co2.fuel + co2.cement + co2.background

co2.bio = co2.bio.gee + co2.bio.resp

co2.fuel = co2.fuel.coal + co2.fuel.oil + co2.fuel.gas + co2.fuel.bio + co2.fuel.waste

co2.fuel + co2.cement = co2.energy + co2.industry + co2.transport + co2.residential + co2.other_categories

Step 4: Animate the footprints

By default the footprint for the central time step of the time series is displayed on the map. You can step through time with ‹ and ›, or display a continuous animation of the footprints with ▶.

More options:

  • Zoom in on time axis to display selected range of the time series
  • Zoom in on concentration axis
  • Zoom in on footprint map
  • Show / hide station symbol on footprint map
