Overview
The Southern Great Plains (SGP) atmospheric observatory was the first field measurement site established by the Atmospheric Radiation Measurement (ARM) user facility. This observatory is the world’s largest and most extensive climate research facility.
Scientists use data from the SGP to learn about cloud, aerosol, and atmospheric processes, which in turn leads to improvements in models of the Earth’s climate.
