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.
Climate Observations and Monitoring (COM)-supported research provides evidence to reconcile a long-standing debate on identifying the mechanisms underlying the Atlantic Multidecadal Variability.
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.
Research supported by the Climate Variability & Predictability (CVP) program challenges long-standing beliefs on what led to the development of the 1970s Great Salinity Anomaly and resulting shutdown of the Labrador Sea deep convection.

Climate Variability & Predictability (CVP)-funded researchers find that a common Southern Ocean bias in CMIP5 climate models is due to errors in the simulated ocean circulation.

Better prediction of the Madden-Julian Oscillation (MJO) can lead to better prediction in related meteorological variables, such as precipitation. However, the relationship between MJO skill and the predictive potential for meteorological variables is complex, as this Climate Variability & Predictability (CVP)-supported study shows.
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.
