For stratospheric aerosols, four subtypes are introduced: polar stratospheric aerosol type, volcanic ash type, sulfate/other type and smoke type, taking into account γ ', δpest, top-bottom height, location, month and surface type.\n<img alt=\"\" src=\"/static/upload/images/20250506163808jiagongguocheng.png\" /></p>",
