Global Monitoring Division
Providing the best possible information on atmospheric constituents that drive climate change, stratospheric ozone depletion, and baseline air quality.
ESRL's Global Monitoring Division conducts sustained observations and research related to global distributions, trends, sources and sinks of atmospheric constituents that are capable of forcing change in the climate of the Earth. This research will advance climate projections and provide scientific policy-relevant, decision support information to enhance society's ability to plan and respond.Read More...
ESRL's Global Monitoring Division conducts research on the depletion of the global stratospheric ozone layer and Antarctic ozone hole through global surface-based monitoring of total-column ozone, ultraviolet radiation, and ozone-depleting gases, including those regulated by the Montreal Protocol. Continued surveillance is necessary in order to verify the expected recovery of the ozone layer.Read More...
Baseline Air Quality
ESRL's Global Monitoring Division monitors levels of air quality elements such as tropospheric ozone, carbon monoxide and aerosol particles in non-source regions which may be affected by long range transport from distant sources of industrial pollution. This large-scale transport affects baseline air quality which must be monitored in order to determine the importance of regional sources that may impact the environment and public health.Read More...
