Understanding Wildfire Emissions From Flaming to Smoldering Using Satellite Data

AC4-funded research finds that data from the Tropospheric Monitoring Instrument (TROPOMI) illuminates key changes in wildfire emissions and impacts that occur while a fire evolves from intense flames to smoldering conditions, emphasizing the value of space-based observations to inform forecasts and models.

Air Quality and Health Impacts from Prescribed Burns in the Eastern US

Apart from wildfires, air quality and health challenges are also created by planned burns in grasslands, shrublands, and farmland. Few studies have investigated how different crops or plant types may contribute to air pollution when burned. The Climate Program Office’s Atmospheric Chemistry, Carbon Cycle and Climate (AC4) Program supported a new study that looks into emissions of

Detecting Carbon Dioxide Emissions in Salt Lake City During the COVID-19 Lockdown

Using the “natural experiment” created by the significant reduction in emissions during mandated COVID-19 lockdown measures, researchers funded by AC4 and COM, two programs at the NOAA Climate Program Office, quantified human impacts on the urban atmosphere in Salt Lake City and evaluated the stationary and mobile monitoring systems in place.

Improving Experimental Methods to Study Air Pollution by Nitrogen Species

Nitrogen reacts with oxygen and other chemical compounds to form atmospheric oxides, which significantly impact the chemical composition of our atmosphere, human and environmental health, and broader climate processes. These gases can be produced by a range of natural and anthropogenic sources including fossil fuel combustion and wildfires. The atmospheric chemistry research community has developed new methods to track the emission sources of these gases and their key chemical reactions by analyzing the stable isotopes of nitrogen and oxygen in the gas compounds. However, there is a lack of a well-established method to simultaneously differentiate and quantify the concentration and isotopic composition of multiple groups of nitrogen oxides.
