The gases and particles released from wildfires impact air quality and climate, so it is important to understand the chemical composition of these emissions. In current air quality forecasts and climate models, the composition of wildfire emissions is based on the dominant vegetation burned and is assumed to be constant over time. In contrast, measurements from laboratory burns indicate that the composition of emissions from fires changes over time, as fires progress from more flaming combustion to flameless burning dominated by smoke (smoldering). It is challenging to have daily field measurements of the emissions from long-lived wildfires, but there are instruments in space that can make daily observations of wildfires globally. In this study, we show how the composition of emissions from wildfires in California, Oregon, and Washington changed over time, as they progressed from more flaming to more smoldering combustion, using observations from a satellite instrument called TROPOMI. The analysis of the composition of wildfire emissions and their evolution over time using TROPOMI could improve air quality forecasting and climate modeling globally. Major findings: A 2023 study used the TROPOMI satellite instrument to track how the chemical composition of wildfire smoke changes as fires evolve. By analyzing 15 large wildfires in the Western U.S., researchers discovered that the ratio of nitrogen dioxide (NO2) to carbon monoxide (CO) drops significantly as a fire moves from its "flaming" stage to its "smoldering" stage. This is a vital finding because current air quality forecasts often assume smoke composition stays the same throughout a fire's duration. Using daily satellite observations allows scientists to see these shifts in real-time, even when ground-based measurements are unavailable. This information helps improve models that predict how wildfire smoke will impact public health and the global climate over several weeks. https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 http://www.w3.org/2000/01/rdf-schema#label Analyzing the Impact of Evolving Combustion Conditions on the Composition of Wildfire Emissions Using Satellite Data https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://schema.org/funder https://ror.org/021nxhr62 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://w3id.org/fdof/ontology#hasMetadata https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://www.w3.org/ns/dcat#contactPoint joost.degouw@colorado.edu https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://www.w3.org/ns/dcat#endDate 2023 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://www.w3.org/ns/dcat#startDate 2022 https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/provenance https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0009-0008-8411-2742 https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/pubinfo https://orcid.org/0009-0008-8411-2742 http://xmlns.com/foaf/0.1/name Emily Regalado https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/dc/terms/created 2026-01-21T17:47:08.691Z https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/dc/terms/creator https://orcid.org/0009-0008-8411-2742 https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/nanopub/x/introduces https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/nanopub/x/supersedes https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg http://purl.org/nanopub/x/wasCreatedAt https://nanodash.knowledgepixels.com/ https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RA0J4vUn_dekg-U1kK3AOEt02p9mT2WO03uGxLDec1jLw https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RAoTD7udB2KtUuOuAe74tJi1t3VzK0DyWS7rYVAq1GRvw https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RAukAcWHRDlkqxk7H2XNSegc1WnHI569INvNr-xdptDGI https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RArM5GTwgxg9qslGX-XiQ-KTTUwdoM0KB1YqmT4GqTizA https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/sig http://purl.org/nanopub/x/hasPublicKey MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxzr6UBGMW6c8tegz0babaledWUEQ0PLDE4tp7Iinbe2DZtAtY5JUptKYuStWDZx+QER4808P8dejNWRnBDzgthYJm/AyNSXflHSJhz2+NC+h7RylOLxbwLEQocmyKKiYxa2gT85m6ajVL2M6TnfG67nnK+K2f7iCGL6wYXRITD1q+7+5SWqBdDXIV921W4IKWaD2GJk+NRBoOqQhbsrk8Tn5XsNd7DMYVHk47oMDGbeBnrOIoRPsbBgAcoCsxxhiB9yN6Lf8EUbnlXVEDzJuZk048L1BDZL+6nkA8btTQGP2ijUFWA7rTrod3LjUDQWLZS95njjl867dtmv/znYkzwIDAQAB https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/sig http://purl.org/nanopub/x/hasSignature HUWZHs9l2eKpwiaQFR9821nXCw1tQznUsy6+ZZBmXqTAsiUmDpYXhWrsXWZaiZUB4/RBOfM7fqNy0VmxOpfi9K5S8SNXwoRRfk5NAC3GPu8IKIVdQbPFwNp1SAaJ2M6gd0TcBevlmiJxz+oyVloU5kBOT72tV/+LlPefKSwSdatLzDvvZgK2k5kOC2FkvzgErZxFmHAvuxMJge4TJuEJ/Vft7mzlFnGEpbobO5n6Z4+x0QgAvmLBjIDuugLXk3BnXAolAcFx84TT8efPg+CTZvxfZewUy5ZAUdK0+d4YImee+BCd7P4yUjcoiAuziOG5H6LD95Zo6q8xqSCdLUd56w== https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg https://w3id.org/np/RAYu_PIj0XJEvKNFFa0upjHL7Y4nMPhowWEH0qfT6T2Lg/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0009-0008-8411-2742
