The definition of threshold values of monitored parameters which are used to identify moderate and severe SW events is one of the critical problems. Due to the lack of both physical data on severe events and user feedback, we tried to approach the problem statistically. In particular, we pursued the answer to the question about what intensity of ionospheric storms and flare effects should be reported by national and global SW entities to their users. We also discussed the possible role of an active region on the Sun, and the cosmic rays\u2019 issues that may be helpful regarding SW operational work. The presented considerations are based on examples of the ionosphere state assessment for the low-latitude American sector with a focus on the Mexican region. This work attempts to argue the possible approaches to resolve the tasks that the SW national services and global centers face.<\/jats:p>","DOI":"10.3390\/rs15194839","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T07:49:29Z","timestamp":1696578569000},"page":"4839","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["On Some Challenges for National and Global Space Weather Services"],"prefix":"10.3390","volume":"15","author":[{"given":"Maria A.","family":"Sergeeva","sequence":"first","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"},{"name":"CONAHCYT, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4774-1829","authenticated-orcid":false,"given":"Juan Americo","family":"Gonzalez-Esparza","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Victor Jose","family":"Gatica-Acevedo","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Luis Xavier","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"},{"name":"CONAHCYT, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Pedro","family":"Corona-Romero","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"},{"name":"CONAHCYT, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1136-585X","authenticated-orcid":false,"given":"Ernesto","family":"Aguilar-Rodriguez","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7221-6500","authenticated-orcid":false,"given":"Angela","family":"Melgarejo-Morales","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Isaac David","family":"Orrala-Legorreta","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Julio Cesar","family":"Mejia-Ambriz","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"},{"name":"CONAHCYT, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"}]},{"given":"Jose Juan","family":"Gonzalez-Aviles","sequence":"additional","affiliation":[{"name":"SCiESMEX, LANCE, Instituto de Geofisica, Unidad Michoacan, Universidad Nacional Autonoma de Mexico, Morelia 58089, Michoacan, Mexico"},{"name":"Escuela Nacional de Estudios Superiores, Unidad Morelia, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Morelia 58190, Michoacan, Mexico"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"563","DOI":"10.1023\/A:1005107532631","article-title":"Ionospheric storms\u2014A review","volume":"88","author":"Buonsanto","year":"1999","journal-title":"Space Sci.
