The instrument provides infrared soundings of unprecedented accuracy and spectral resolution to derive humidity and atmospheric temperature profiles, as well as some of the chemical components playing a key role in climate monitoring. IASI collects rich spectral information, which results in large amounts of data (about 16 Gigabytes per day). Efficient compression techniques are requested for both transmission and storage of such huge data. This study reviews the performance of several state of the art coding standards and techniques for IASI L1C data compression. Discussion embraces lossless, near-lossless and lossy compression. Several spectral transforms, essential to achieve improved coding performance due to the high spectral redundancy inherent to IASI products, are also discussed. Illustrative results are reported for a set of 96 IASI L1C orbits acquired over a full year (4 orbits per month for each IASI-A and IASI-B from July 2013 to June 2014) . Further, this survey provides organized data and facts to assist future research and the atmospheric scientific community.<\/jats:p>","DOI":"10.3390\/s17061404","type":"journal-article","created":{"date-parts":[[2017,6,16]],"date-time":"2017-06-16T10:06:31Z","timestamp":1497607591000},"page":"1404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Hyperspectral IASI L1C Data Compression"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3808-7132","authenticated-orcid":false,"given":"Joaqu\u00edn","family":"Garc\u00eda-Sobrino","sequence":"first","affiliation":[{"name":"Department of Information and Communications Engineering, Universitat Aut\u00f2noma de Barcelona, 08193 Bellaterra, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4729-9292","authenticated-orcid":false,"given":"Joan","family":"Serra-Sagrist\u00e0","sequence":"additional","affiliation":[{"name":"Department of Information and Communications Engineering, Universitat Aut\u00f2noma de Barcelona, 08193 Bellaterra, Spain"}]},{"given":"Joan","family":"Bartrina-Rapesta","sequence":"additional","affiliation":[{"name":"Department of Information and Communications Engineering, Universitat Aut\u00f2noma de Barcelona, 08193 Bellaterra, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2017,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1002\/qj.49712454510","article-title":"The information content of clear sky IASI radiances and their potential for numerical weather prediction","volume":"124","author":"Prunet","year":"1998","journal-title":"Q.
