This study, funded in part by Atmospheric Chemistry, Carbon Cycle, & Climate (AC4), investigates the relationship between primary and secondary sources of organic aerosols over the lifetime of a wildfire plume, finding at least half of the secondary sources are the result of evaporation of the primary sources.
Researchers supported in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program have collected new aerosol data at two coastal sites on the North Slope of Alaska. Their work, combined with past data from NOAA, reveals that sulfur aerosol concentrations continue to increase at more than 2% per year.
Published as a NOAA Technical Report, this white paper identifies the NOAA mission requirements, stakeholder mandates, and seven science and operational application areas that will benefit from geostationary satellite instruments providing atmospheric composition products.
Atmospheric Chemistry, Carbon Cycle, & Climate (AC4)-funded researchers determine acyl peroxynitrate, one possible result from nitrogen oxide (NOx) reacting in the atmosphere, can act as a NOx sink rather than a reservoir in rural and remote forested regions.
Researchers funded in part by AC4 have developed a fire prediction model which incorporates multiple machine learning algorithms to better predict areas burned by wildfire in the US south central region.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
