The optical design of the spectrometer involves freeform optics, which enables achieving exceptional performance and allows progressing well beyond the state-of-the-art in terms of compactness, field-of-view, and spatial resolution. The spectrometer is intended to be launched on a small satellite orbiting at 700 km and observing the Earth with a wide field-of-view of 120\u00b0 and a spatial resolution of 2.6 km at nadir. The satellite will ultimately allow for improved climate change monitoring.<\/jats:p>","DOI":"10.3390\/s22155841","type":"journal-article","created":{"date-parts":[[2022,8,5]],"date-time":"2022-08-05T02:12:39Z","timestamp":1659665559000},"page":"5841","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Optical Design of a Novel Wide-Field-of-View Space-Based Spectrometer for Climate Monitoring"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6191-7822","authenticated-orcid":false,"given":"Luca","family":"Schifano","sequence":"first","affiliation":[{"name":"Brussels Photonics (B-PHOT), Department of Applied Physics and Photonics, Vrije Universiteit Brussel, Pleinlaan 2, 1050 Brussels, Belgium"},{"name":"Royal Meteorological Institute of Belgium, Avenue Circulaire 3, 1180 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0822-233X","authenticated-orcid":false,"given":"Francis","family":"Berghmans","sequence":"additional","affiliation":[{"name":"Brussels Photonics (B-PHOT), Department of Applied Physics and Photonics, Vrije Universiteit Brussel, Pleinlaan 2, 1050 Brussels, Belgium"},{"name":"Flanders Make, Pleinlaan 2, 1050 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven","family":"Dewitte","sequence":"additional","affiliation":[{"name":"Royal Observatory of Belgium, Avenue Circulaire 3, 1180 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2431-1052","authenticated-orcid":false,"given":"Lien","family":"Smeesters","sequence":"additional","affiliation":[{"name":"Brussels Photonics (B-PHOT), Department of Applied Physics and Photonics, Vrije Universiteit Brussel, Pleinlaan 2, 1050 Brussels, Belgium"},{"name":"Flanders Make, Pleinlaan 2, 1050 Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1836","DOI":"10.1016\/S0140-6736(19)32596-6","article-title":"The 2019 report of The Lancet Countdown on health and climate change: Ensuring that the health of a child born today is not defined by a changing climate","volume":"394","author":"Watts","year":"2019","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"263","DOI":"10.1056\/NEJMra1807873","article-title":"The imperative for climate action to protect health","volume":"380","author":"Haines","year":"2019","journal-title":"N.
