Impact-Sector Applications¶
The Climate DT includes four impact-sector applications that process climate model output to derive sector-specific indicators. These applications are aligned with the Destination Earth use cases and operate as integrated components of the Climate DT workflow.
The applications deliver information at the spatial and temporal resolution of the Climate DT simulations and have been developed in collaboration with users from relevant sectors.
The output can be retrieved from the Destination Earth Data Lake. Instructions are found under Data Access.
Integration within the Climate DT Workflow¶
Impact-sector applications are integrated within the Climate DT production workflow and process data as it is generated by the coupled models (see here). The output from all three models can be processed the same way by the apps due to the Generic State Vector (GSV) that unifies the model output to a large extent. Before the data is processed by the applications the data goes through the One-pass Algorithm and potentially through Bias adjustment.

One-Pass Algorithm (OPA)
The OPA incrementally computes statistical metrics as data becomes available, without requiring access to the full temporal record. Available statistics include percentiles, histograms and annual maxima.
Bias Adjustment (BA)
Bias adjustment can be applied to selected variables using quantile mapping against reference datasets. This component operates within the streaming workflow and is primarily applied to precipitation and temperature. Currently, only HydroLand uses Bias Adjustment.
