The Silverton CO2/CO monitoring site is on a 269m tower located at the eastern edge of Oregon’s Willamette Valley. The site came online in June 2012. It is located east of the town of Silverton in Oregon's central Willamette Valley. Gas analysis is performed with a Picarro 2302 Cavity Ringdown Spectrometer, and the tower is also equipped with a set of meteorological instruments, including an HMP sensor, a radiation sensors, and an anemometer. This site is also part of the PhenoCam network operated by Harvard University and the University of New Hampshire.

The mixing ratio data measured at this this site is available for download at the NOAA ESRL Observation Package (ObsPack) Data Products webpage.
