The European Earth Observation (EO) infrastructure is assessed through of comprehensive end-user need and data gap analysis. This review was based on the top 10 use cases, identifying 20 measurements with gaps and 13 potential EO technologies to cover the identified gaps. It was found that the top priority is the observation of polar regions to support sustainable and safe commercial activities and the preservation of the environment. Additionally, an analysis of the technological limitations based on measurement requirements was performed. Finally, this analysis was used for the basis of the architecture design of a potential polar mission.<\/jats:p>","DOI":"10.3390\/rs10071098","type":"journal-article","created":{"date-parts":[[2018,7,10]],"date-time":"2018-07-10T10:01:46Z","timestamp":1531216906000},"page":"1098","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Gaps Analysis and Requirements Specification for the Evolution of Copernicus System for Polar Regions Monitoring: Addressing the Challenges in the Horizon 2020\u20132030"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0086-6894","authenticated-orcid":false,"given":"Estefany","family":"Lancheros","sequence":"first","affiliation":[{"name":"Universitat Polit\u00e8cnica Catalunya\u2014BarcelonaTech &amp; IEEC, Campus Nord, 08034 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9514-4992","authenticated-orcid":false,"given":"Adriano","family":"Camps","sequence":"additional","affiliation":[{"name":"Universitat Polit\u00e8cnica Catalunya\u2014BarcelonaTech &amp; IEEC, Campus Nord, 08034 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0031-0802","authenticated-orcid":false,"given":"Hyuk","family":"Park","sequence":"additional","affiliation":[{"name":"Universitat Polit\u00e8cnica Catalunya\u2014BarcelonaTech &amp; IEEC, Campus Nord, 08034 Barcelona, Spain"}]},{"given":"Pierre","family":"Sicard","sequence":"additional","affiliation":[{"name":"ACRI B\u00e2timent Le Grand Large, Quai de la Douane\u20142 \u00e8me \u00e9peron, 29200 Brest, France"}]},{"given":"Antoine","family":"Mangin","sequence":"additional","affiliation":[{"name":"ACRI B\u00e2timent Le Grand Large, Quai de la Douane\u20142 \u00e8me \u00e9peron, 29200 Brest, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3374-9846","authenticated-orcid":false,"given":"Hripsime","family":"Matevosyan","sequence":"additional","affiliation":[{"name":"Skolkovo Institute of Science and Technology, Moscow 143026, Russia"}]},{"given":"Ignasi","family":"Lluch","sequence":"additional","affiliation":[{"name":"Skolkovo Institute of Science and Technology, Moscow 143026, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1109\/MGRS.2017.2720263","article-title":"A Value-Chain Analysis for the Copernicus Earth Observation Infrastructure Evolution: A Knowledgebase of Users, Needs, Services, and Products","volume":"5","author":"Matevosyan","year":"2017","journal-title":"IEEE Geosci.
