Artificial climate control might become ineffective

Jun 28, 2024

One regional geoengineering proposal for alleviating the extreme heat effects of global warming, the brightening of marine clouds to reflect more solar energy to space over different limited areas, could work in present-day conditions but may become ineffective in the future, according to new research.

Asian Monsoon Lofts Ozone-Depleting Substances to Stratosphere

Apr 30, 2024

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, new research shows.

Opportunities for Collaboration

Opportunities and Partnerships

ACOM conducts collaborative research focusing on two major scientific challenges, Air Quality Prediction Research and Interactions between Chemistry and the Climate/Weather System. The work is conducted in partnership with other entities within NCAR, and with other members of the wider atmospheric chemistry community.

Model grids used in the spectral element version of the NCAR Community Atmosphere Model (CAM-SE).

Multi-Scale Infrastructure for Chemistry Modeling (MUSICA)

Field Missions and Data Archive

Data collection in the field.

Chemical Forecasts

Generated daily with WACCM, CAM-Chem, and WRF-Chem.
