Editing Ammonia production (mass) (section)

== Aggregation Semantics ==
Geographically, ammonia production data are aggregated at global and regional scales to capture spatial distribution and trends. Temporally, the signal is aggregated periodically, typically on an annual basis, to reflect production cycles and reporting intervals. Cross-signal aggregation may consider ammonia production alongside related environmental signals such as greenhouse gas emissions or nitrogen deposition to assess combined environmental pressures. Aggregations aim to support comparative analysis and integrated assessment within the SIGNAL framework.
