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.

Two new studies supported by the Climate Variability & Predictability (CVP) program offer data-driven insights into the Madden-Julian Oscillation (MJO), the dominant mode of tropical intraseasonal variability.

The future of the El Niño Southern Oscillation, or ENSO, is the subject of a new book published by the American Geophysical Union. 

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.
