    rdfs:comment "Climate change has led to an increase in the frequency and size of wildfires in the Western United States. 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.";
