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.
