STILT Footprint Tool on demand calculator (hosted by ICOS)

The STILT Footprint Tool on-demand calculator service, provided by ICOS, allows registered users to run the STILT model framework to simultaneously identify the regions of influence (“footprints”) and the breakdown of the observable CO2 concentration “signal” into anthropogenic and biogenic contributions at hourly resolution. The outputs can be visualized using the accompanying STILT Footprint Tool viewer service https://stilt.icos-cp.eu/viewer/. This service is of primary interest for greenhouse gas researchers wishing to understand to what extent observation station networks can provide representative coverage of all important sources and sinks of CO2 in the European continent, thus providing a simplified approach towards evaluating different measurement networks and strategies. The current model framework has been developed at the Max Planck Institute for Biogeochemistry and is implemented as a web-based service at the ICOS Carbon Portal. It consists of the Lagrangian transport model STILT (Stochastic Time Inverted Lagrangian Transport; Lin et al., 2003 <https://doi.org/10.1029/2002JD003161>) together with emission-sector and fuel-type specific emissions derived from the EDGAR inventory (EC-JRC) combined with BP fuel consumption statistics, and biospheric flux estimates from the diagnostic biosphere model VPRM (Vegetation Photosynthesis and Respiration Model; Mahadevan et al., 2008 <https://doi.org/10.1029/2006GB002735>). Both the STILT Footprint Tool viewer and STILT Footprint Tool on demand calculator services are provided by ICOS Carbon Portal in the context of ATMO-ACCESS project. Therefore an ATMO-ACCESS login is required to use them.
