Earth System Science and Modeling

Agricultural activities are the main source of nitrous oxide emissions from human activities, but there is limited attention to agriculture as a major contributor to increasing emissions likely from a lack of understanding of mechanisms controlling nitrous oxide emissions.

New research, funded by CPO's Climate Variability and Predictability Program, shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts.

A research team funded in part by CPO's MAPP and CVP Programs investigate the effect of global warming on the MJO. 

On December 4, Colm Sweeney, Aircraft Program lead for the NOAA Global Monitoring Division Carbon Cycle Group and Acting Deputy Director for CPO’s Ocean Observing and Monitoring Division, will present results from an intensive airborne campaign to measure levels of methane, carbon dioxide, carbon monoxide, and ethane emissions from five major cities along the East Coast.

This CPO-supported dataset has resulted in new ways in which the community can examine low frequency climate and it is now in a reliable public data repository for years to come.
