KHO is a unique site that lies underneath the dayside cusp, a funnel-shaped region where particles from the Sun can directly enter the Earth’s upper atmosphere, including the ionosphere. Building on the pioneering observations of its predecessor—the Auroral Station in Adventdalen, Svalbard—KHO has played a pivotal role in advancing our understanding of phenomena in the polar atmosphere. The Auroral Station and KHO have amassed climatological measurements over Svalbard for an impressive 40-year period. KHO’s diverse instrumentation, combined with other co-located optical and radar infrastructure, and in situ measurements from satellites and sounding rockets, has paved the way for impactful multi-instrument studies. Serving as an accessible testbed for instrument development, new types of instruments have recently been installed, both at KHO and on satellites. Beyond its scientific contributions, KHO has become an integral part of the Longyearbyen community, with students, visitors, and locals participating in tours and educational initiatives. This connection underscores KHO’s multi-functional role, not only as a centre for excellent research but also as a vital hub for public outreach and engagement. date: 2025-02-03 date_type: published publisher: Canadian Science Publishing official_url: https://doi.org/10.1139/as-2024-0009 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2357633 doi: 10.1139/as-2024-0009 lyricists_name: Aruliah, Anasuya lyricists_id: ALARU69 actors_name: Aruliah, Anasuya actors_id: ALARU69 actors_role: owner full_text_status: public publication: Arctic Science volume: 11 pagerange: 1-25 issn: 2368-7460 citation: Herlingshaw, Katie; Partamies, Noora; van Hazendonk, Charlotte M; Syrjäsuo, Mikko; Baddeley, Lisa J; Johnsen, Magnar G; Eriksen, Nina K; ...
