Ilmiasuihin

Ilmiasuihin is a term used in Finnish environmental science and meteorology to refer to phenomena, processes, and models related to the atmosphere. The word combines ilma, meaning air, with a suffix that signals a focus on atmospheric aspects. In practice, ilmiasuihin denotes the study of how airborne substances—pollutants, aerosols, greenhouse gases, and naturally occurring constituents—are emitted, transformed, transported, and deposited in the atmosphere.

Scope and concepts: Ilmiasuihin encompasses sources (anthropogenic and natural), chemical transformations, transport mechanisms (advection, convection, turbulence), and removal processes (dry and wet deposition). It covers atmospheric composition, radiation interactions, and the interplay between chemistry and physics within the troposphere and stratosphere.

Measurement and modeling: The field includes observational methods such as ground-based monitoring stations, aircraft campaigns, lidar, and satellite remote sensing, as well as numerical models like chemical transport models, regional air-quality models, and climate models with chemistry components. Data interpretation often involves uncertainty assessment, model intercomparison, and scenario analysis.

Applications: Ilmiasuihin is referenced in scientific articles, policy reports, and environmental impact assessments to describe atmospheric processes, air quality issues, and climate-chemistry interactions. In Finnish-language sources it is typically used in technical contexts; English-language translations might employ atmospheric chemistry or air-quality science.
