Spatial allocation decides how an emission total is represented across locations. The aim is a spatial account consistent with its source total and appropriate for the downstream research scale.
Distinguish individually located sources, area sources and regional totals. Decide which representation is justified by source knowledge and how boundaries relate across maps. State the intended scale of interpretation.
Select allocation indicators for their relationship to the sources represented. Explain their coverage and what happens where an indicator is absent or has no allocation support. A fallback rule changes the interpretation and belongs in the method rationale.
Keep projection, grid orientation, area coverage and reporting units consistent. A visually aligned map can still represent a different area or quantity.
Plan checks that allocation preserves the intended total, excludes unintended duplication and respects the valid domain. When changing resolution, match aggregation to the physical quantity; an extensive total and a concentration need different treatment.
Explain uncertainty from source locations, allocation indicators and boundary changes. A finer grid does not by itself supply finer source knowledge.
Describe required temporal, vertical and chemical-species correspondence at the conceptual level. The accounting method supplies the shared source boundary. The input planning entry records method choices; this page contains no concrete data, settings or implementation.
