The Global Monitoring Laboratory (GML) of the National Oceanic and Atmospheric Administration conducts research that addresses three major challenges: greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, and surface radiation, and recovery of stratospheric ozone.

2022 Global Monitoring Annual Conference

The Global Monitoring Laboratory will hold a virtual conference for the 2022 Global Monitoring Annual Conference. The 2022 virtual GMAC (eGMAC) will be held on five consecutive days: Monday, May 23th through Friday, May 27th, 2022.

Themes

Greenhouse Gases and Carbon Cycle Feedbacks

Changes in Surface Radiation, Clouds, and Aerosols

Recovery of Stratospheric Ozone

Programs

Carbon Cycle Greenhouse Gases

Measurments and modeling of the spatial and temporal distributions of greenhouse gases, providing constraints to our understanding of the global carbon cycle.

Halocarbons and other Trace Species

Quantifying the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases.

Global Radiation and Aerosols

Empirical and theoretical research of the Earth's surface radiation budget and characterizing variability and trends of climate-forcing properties of aerosol particles.

Ozone and Water Vapor

Research on the nature and causes of the depletion of the stratospheric ozone layer and the role of ozone and water vapor in forcing climate change.
