We Welcome Dr. Ariel Stein as the new Director of GML.
Former GML Director, James Butler, retired after decades of contributions to the global scientific community.
Read about his many contributions here.
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.



greenhouse gases
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.

hats group
Halocarbons and other Trace Species

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

grad group
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
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.
