Virtual Joint Field Campaign

Figure for scientific publication

A group of authors from the DFG-funded Cosmic Sense project wrote a model experiment description paper about a virtual joint field campaign (vJFC). The vJFC is one of the cross-cutting activities of the project, bringing together the expertise of many project partners. The idea is to create and provide a virtual study site with which all partners can conduct their observations and simulations and reconstruct the target variable. The results of these simulations can then be compared to the original virtual site, allowing for analysis, validation and comparison that is not feasible in a real-world setting. I sketched the concept and workflow of the vJFC.

The concept of the vJFC and used terminology: “Compartments” are independent components of the landscape that can be constructed with desired characteristics. Selected compartments are merged to form a specific “realization” of a landscape. This virtual landscape can then be probed with different “virtual sensors” (i.e. models) to yield “virtual observations”. These observations can drive methods for reconstructing the target variable of interest. The virtual observations directly and/or the estimates derived thereof can then be analyzed, e.g. compared to the original virtual truth.

Another figure describes the different modi of combining individual compartments to create the model domain.
