Industry is one of the largest anthropogenic sources of methane, which are currently only roughly estimated. New satellite hyperspectral imagers, such as PRISMA, open up daily temporal monitoring of industrial methane sources at a spatial resolution of 30 m. Here, we developed the Characterization of Effluents Leakages in Industrial Environment (CELINE) code to inverse images of the Korpezhe industrial site. In this code, the in-Scene Background Radiance (ISBR) method was combined with a standard Optimal Estimation (OE) approach. The ISBR-OE method avoids the use of a complete and time-consuming radiative transfer model. The ISBR-OEM developed here overcomes the underestimation issues of the linear method (LM) used in the literature for high concentration plumes and controls a posteriori uncertainty. For the Korpezhe site, using the ISBR-OEM instead of the LM -retrieved CH4 concentration map led to a bias correction on CH4 mass from 4 to 16% depending on the source strength. The most important CH4 source has an estimated flow rate ranging from 0.36 \u00b1 0.3 kg\u00b7s\u22121 to 4 \u00b1 1.76 kg\u00b7s\u22121 on nine dates. These local and variable sources contribute to the CH4 budget and can better constrain climate change models.<\/jats:p>","DOI":"10.3390\/rs13244992","type":"journal-article","created":{"date-parts":[[2021,12,8]],"date-time":"2021-12-08T23:30:00Z","timestamp":1639006200000},"page":"4992","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Joint Use of in-Scene Background Radiance Estimation and Optimal Estimation Methods for Quantifying Methane Emissions Using PRISMA Hyperspectral Satellite Data: Application to the Korpezhe Industrial Site"],"prefix":"10.3390","volume":"13","author":[{"given":"Nicolas","family":"Nesme","sequence":"first","affiliation":[{"name":"ONERA, The French Aerospace Lab, D\u00e9partement Optique et Techniques Associ\u00e9es (DOTA), 31000 Toulouse, France"},{"name":"SPASCIA, Space Science Algorithm, 31520 Ramonville, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5585-4335","authenticated-orcid":false,"given":"Rodolphe","family":"Marion","sequence":"additional","affiliation":[{"name":"CEA, Direction des Applications Militaires Ile-de-France, 91290 Arpajon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3182-6572","authenticated-orcid":false,"given":"Olivier","family":"Lezeaux","sequence":"additional","affiliation":[{"name":"SPASCIA, Space Science Algorithm, 31520 Ramonville, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00e9phanie","family":"Doz","sequence":"additional","affiliation":[{"name":"ONERA, The French Aerospace Lab, D\u00e9partement Optique et Techniques Associ\u00e9es (DOTA), 31000 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claude","family":"Camy-Peyret","sequence":"additional","affiliation":[{"name":"Institut Pierre Simon Laplace, 75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0435-4573","authenticated-orcid":false,"given":"Pierre-Yves","family":"Foucher","sequence":"additional","affiliation":[{"name":"ONERA, The French Aerospace Lab, D\u00e9partement Optique et Techniques Associ\u00e9es (DOTA), 31000 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"45005","DOI":"10.1088\/1748-9326\/ab751d","article-title":"Methane emissions from underground gas storage in California","volume":"15","author":"Thorpe","year":"2020","journal-title":"Environ.
