Burns CO2 Observation Site

Sagebrush at Burns tower

Latitude: 43.4712
Longitude: -119.691
1398 masl
Intake Heights: 
18.5, 28.5, and 38.5 meters above ground
Gases Measured: 

CO2, CO, H2O


The site was established in 2012 and is part of a NOAA observation network for high precision measurements of carbon dioxide concentrations. It is located about 60 km southwest of Burns, Oregon in the Oregon High Desert. The vegetation in this area is dominated by sagebrush. The sampling inlets are at the heights of 18.5, 28.5, and 38.5 m. Gas analysis is performed with a Picarro 2302 Cavity Ringdown Spectrometer and a Li-Cor 7200 enclosed path IRGA. The tower is also equipped with a set of meteorological instruments, including an HMP sensor, radiation sensors (incoming and diffuse PAR, Net radiometer), and a CSAT3 sonic anemometer. Phenocam
