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/02w0trx84 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://w3id.org/fdof/ontology#hasMetadata https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI 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/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/provenance https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0009-0008-8411-2742 https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/pubinfo https://orcid.org/0009-0008-8411-2742 http://xmlns.com/foaf/0.1/name Emily Regalado https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI http://purl.org/dc/terms/created 2026-01-14T05:58:44.042Z https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI http://purl.org/dc/terms/creator https://orcid.org/0009-0008-8411-2742 https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI http://purl.org/nanopub/x/introduces https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL105811 https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI http://purl.org/nanopub/x/wasCreatedAt https://nanodash.knowledgepixels.com/ https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/o/ntemplate/wasCreatedFromProvenanceTemplate https://w3id.org/np/RA7lSq6MuK_TIC6JMSHvLtee3lpLoZDOqLJCLXevnrPoU https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RA0J4vUn_dekg-U1kK3AOEt02p9mT2WO03uGxLDec1jLw https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/o/ntemplate/wasCreatedFromPubinfoTemplate https://w3id.org/np/RAukAcWHRDlkqxk7H2XNSegc1WnHI569INvNr-xdptDGI https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RArM5GTwgxg9qslGX-XiQ-KTTUwdoM0KB1YqmT4GqTizA https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/sig http://purl.org/nanopub/x/hasPublicKey MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxzr6UBGMW6c8tegz0babaledWUEQ0PLDE4tp7Iinbe2DZtAtY5JUptKYuStWDZx+QER4808P8dejNWRnBDzgthYJm/AyNSXflHSJhz2+NC+h7RylOLxbwLEQocmyKKiYxa2gT85m6ajVL2M6TnfG67nnK+K2f7iCGL6wYXRITD1q+7+5SWqBdDXIV921W4IKWaD2GJk+NRBoOqQhbsrk8Tn5XsNd7DMYVHk47oMDGbeBnrOIoRPsbBgAcoCsxxhiB9yN6Lf8EUbnlXVEDzJuZk048L1BDZL+6nkA8btTQGP2ijUFWA7rTrod3LjUDQWLZS95njjl867dtmv/znYkzwIDAQAB https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/sig http://purl.org/nanopub/x/hasSignature qYEmiAWrCcCs08ZCj30cvyq1jTXwVpAHD0+GIFc9doxB5nhIqnFu97KWWTBhUBTvi+QK34+UsnFIdOOeje1BNFhRukLw1cRlgAFRiAnUvz5t5MpxGRVKWAifGEYCULHBfmkOfN93pMxex+33t/mJ7GCu6q5oBe5HZUWUDiERcQ9eG2eGEOGG81Cyny+EEhZT8SC4l0p4ByB5vGVS3740PmlJ69sNSUu+Scv+7Q3Lti/A+Y/ckCR3bUC5F+7zTS1ij+kL4431OOhyXZa6JTNlVck1HgzGIVwRh7Hb8FIk5+uVi5Z0ZhIIJypPuY33ny6eCjpC5/tzi7E+OJltr478WA== https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI https://w3id.org/np/RAr3lSue083Rb_cO11j34T1xGmmT-wZaNEUCRsWxbdVEI/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0009-0008-8411-2742
