This C-band dual-polarization Doppler weather radar is new to the suite of instruments available at the ARM Climate Research Facility site in Oklahoma.
The United States Department of Energy's Atmospheric Radiation Measurement (ARM) Program was created in 1989 to develop several highly instrumented ground stations to study cloud formation processes and their influence on radiative transfer. This scientific infrastructure now includes two mobile facilities, an aerial facility, and data archive available for use by scientists worldwide through the ARM Climate Research Facility—a scientific user facility. A primary objective of the facility is improved scientific understanding of the fundamental physics related to interactions between clouds and radiative feedback processes in the atmosphere. ARM focuses on obtaining continuous field measurements and providing data products that promote the advancement of climate models.
