Terra-PNW Research Sites

The Terra-PNW Research Group operates and maintains seven research stations in Oregon, from the coastal mountains to the high desert. Three of these stations (Marys River Fir, Metolius Young Pine, Metolius Intermediate Pine) are part of the AmeriFlux network. The stations (Burns, Silverton, Walton, and Marys Peak) are also equipped with Laser Cavity Ring-Down Spectrometers for the CO2 observation project.

AmeriFlux Eddy Covariance Sites

The AmeriFlux sites measure carbon and water vapour exchange in successional stages of Pacific Northwest forest ecosystems, integrating eddy flux, plant, and soil measurements. The sites are fully instrumented with infrared gas analyzers (IRGAs), soil respiration measurement chambers, and a complete suite of meteorological sensors. The sites are in remote locations and most are powered by solar, wind, and backup generator sources.

CO2 Observation Sites

We use atmospheric observations of CO2 in inverse modelling to better understand causes of variability in carbon cycling. We are developing a data assimilation approach that combines data from various sources and advanced statistics to constrain and diagnose simulated terrestrial carbon processes using several process models. We established a ground-based network of CO2/CO observation sites in Oregon using Cavity Ring-Down Spectrometers (CRDS) to create a data-rich environment in a confined region with incoming air from the Pacific Ocean and pronounced surface flux heterogeneity that can serve as a test environment for larger scale applications.
