Calculating CO2 and H2O eddy covariance fluxes from an enclosed gas analyzer using an instantaneous mixing ratio

Creator:: Burba, George, Schmidt, Andres, Scott, Russell L., Nakai, Taro, Kathilankal, James, Fratini, Gerardo, Hanson, Chad, Law, Beverly, McDermitt, Dayle K., Eckles, Robert, Furtaw, Michael, and Velgersdyk, Michael
Abstract:: Eddy covariance flux research has relied on open- or closed-path gas analyzers for producing estimates of net ecosystem exchange of carbon dioxide (CO₂) and water vapor (H₂O). The two instruments have had different challenges that have led to development of an enclosed design that is intended to maximize strengths and...

Eddy covariance measurements with a new fast-response, enclosed-path analyzer: Spectral characteristics and cross-system comparisons

Creator:: Novick, K. A., Walker, J., Chan, W.S., Schmidt, A., Sobek, C., and Vose, J. M.
Abstract:: A new class of enclosed path gas analyzers suitable for eddy covariance applications combines the advantages of traditional closed-path systems (small density corrections, good performance in poor weather) and open-path systems (good spectral response, low power requirements), and permits estimates of instantaneous gas mixing ratio. Here, the extent to which...

Providing the best turbulent heat flux estimates from eddy correlation and bulk methods using DYNAMO data

Creator:: Marion, June Raven
Abstract:: In this thesis, data collected during the Dynamics of the Madden Julian Oscillation (DYNAMO) field campaign, conducted in the Indian Ocean in Fall of 2011, is used to compute heat fluxes at the air-sea interface by evaluating eddy covariances and bulk aerodynamic formulae. Errors in daily average gridded fluxes computed...

Empirical assessment of uncertainties of meteorological parameters and turbulent fluxes in the AmeriFlux network

Creator:: Schmidt, Andres, Hanson, Chad, Chan, W. Stephen, and Law, Beverly E.
Abstract:: Terrestrial ecosystem-atmosphere exchange of carbon, water vapor, and energy has been measured for over a decade at many sites globally. To minimize measurement and analysis errors, quality assurance data have been collected over short periods along-side tower instruments at AmeriFlux research sites. Theoretical and empirical error and uncertainty values have...

The suitability of optical particle counters for covariance estimates of the dry deposition velocity of particulate aerosols

Creator:: Hubbe, John McBain
Abstract:: Experimental work at the 1982 Dry Deposition Intercomparison Experiment (DDIEx) involved the use of optical particle counters for covariance estimates of dry deposition velocities of accumulation mode aerosols. Meteorological and particle flux observations are presented. Deposition velocity estimates exhibit scatter about zero. A formulation of the standard error of the...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...

Satellite observations of the inﬂuence of mesoscale ocean eddies on near-surface temperature, phytoplankton and surface stress

Creator:: Gaube, Peter
Abstract:: The influence of mesoscale ocean eddies on near-surface ocean temperature, surface stress and phytoplankton communities is investigated by collocating numerous satellite measurements along with vertical profiles of oceanic temperature and salinity to the interiors of eddies identified and tracked in altimetric sea surface height maps. The surface currents associated with...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...
