Local wind patterns are related to wind at a reference station (Lakollen, 235 m.a.s.l.). The wind frequency distributions for shorter periods are related to a &#8220;normal&#8221; wind distribution. A relationship between observed smoke dispersion and -transport from Her\u00f8ya and observed wind and lapse rate (stability) in the atmosphere around Her\u00f8ya is established, to evaluate the typical wind\/stability &#8211; frequency distribution for a &#8220;model-year&#8221;. Dispersion models (multiple-source-, area-source- and single-stack-types) based on Gaussian distributed concentration profiles are applied to calculate seasonal and annual average ground-level concentration distributions (&#8220;dispersion patterns&#8221;). These dispersion patterns are presented on topographical maps for different emission conditions, and represent a basis for area planning through their visualization of the areas which might be exposed for air pollution in the future.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 15:06:07","footnotes":""},"nva_tax_category":[1095],"class_list":["post-121399","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-report"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/121399","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/121399\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=121399"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=121399"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
