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, and also collect data for the CO2 concentration network.
The other three stations (Burns, Silverton, Walton, and
Marys Peak) have a more limited set of instrumentation and collect data for the CO2
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 modeling 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 (e.g.
CLM4) (NOAA support). We established a ground-based network of CO2
observation sites in Oregon to create a relatively 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. These data are submitted to CarbonTracker.
