Research Groups

ccgg

Global Greenhouse Gas Reference Network

The GGGRN makes measurements of the spatial and temporal distributions of greenhouse gases and provides essential constraints to our understanding of the global carbon cycle.

hats

Halocarbons and other Trace Species

The HATS group quantifies the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases.

aero

Aerosols

The goals of this program are to characterize means, variability, and trends of climate-forcing properties of different types of aerosols.

grad

Global Radiation

Activities involve empirical and theoretical research of the Earth's surface radiation budget.

ozwv

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.

obop
