Creator:: Shum, C. K., Woodworth, P. L., Andersen, O. B., Egbert, Gary D., Francis, O., King, C., Klosko, S. M., Le Provost, C., Li, X., Molines, J-M., Parke, M. E., Ray, Richard D., Schlax, M. G., Stammer, D., Tierney, C. C., Vincent, P., and Wunsch, C. I.
Abstract:: Over 20 global ocean tide models have been developed since 1994, primarily as a consequence of analysis of the precise altimetric measurements from TOPEX/POSEIDON and as a result of parallel developments numerical tidal modeling and data assimilation. This paper provides an accuracy assessment of 10 such tide models and discusses...

Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Introduction to special section on Recent Advances in the Study of Optical Variability in the Near-Surface and Upper Ocean

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

Tropical data assimilation experiments with simulated data: The impact of the Tropical Ocean and Global Atmosphere Thermal Array for the Ocean

Creator:: Miller, Robert N.
Abstract:: A series of observing system simulation experiments (OSSE) is performed on a simulated data set which was designed to mimic the wind-forced response of the tropical Pacific ocean. This data set was constructed by adding random perturbations to the FSU monthly mean pseudostress anomaly data. These perturbed pseudostress anomaly fields...

Distant effect of assimilation of moored currents into a model of coastal wind-driven circulation off Oregon

Creator:: Kurapov, Alexander, Allen, John S., Egbert, Gary D., Miller, Robert N., Kosro, P. Michael, Levine, Murray D., and Boyd, Timothy John, 1958-2013
Abstract:: An optimal interpolation (OI) sequential algorithm is implemented for a three-dimensional primitive equation model to assimilate current measurements from acoustic Doppler profilers moored on the Oregon shelf as a part of the Coastal Ocean Advances in Shelf Transport (COAST) upwelling experiment (May–August 2001). A stationary estimate of the forecast error...

A nested grid model of the Oregon Coastal Transition Zone: Simulations and comparisons with observations during the 2001 upwelling season

Creator:: Springer, S. R., Samelson, Roger M., Allen, John S., Egbert, Gary D., Kurapov, Alexander, Miller, Robert N., and Kindle, J. C.
Abstract:: The Oregon Coastal Transition Zone (OCTZ) extends several hundred kilometers offshore where shelf flows interact with the northern California Current. A primitive-equation numerical ocean model is used to study the upwelling circulation in this region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary conditions...

Mapping tropical Pacific sea level: Data assimilation via a reduced state space Kalman filter

Creator:: Cane, Mark A., Kaplan, Alexey, Miller, Robert N., Tang, Benyang, Hackert, Eric C., and Busalacchi, Anthony J.
Abstract:: The well-known fact that tropical sea level can be usefully simulated by linear wind driven models recommends it as a realistic test problem for data assimilation schemes. Here we report on an assimilation of monthly data for the period 1975-1992 from 34 tropical Pacific tide gauges into such a model...

Estimates of sea surface height and near-surface alongshore coastal currents from combinations of altimeters and tide gauges

Creator:: Saraceno, M., Strub, P. Ted, and Kosro, P. Michael, 1951-
Abstract:: Present methods used to retrieve altimeter data do not provide reliable estimates of sea surface height (SSH) in the nearshore region, resulting in a measurement gap of 25–50 km next to the coast. In the present work, gridded SSH fields produced by Archiving, Validation, and Interpretation of Satellite Oceanographic data...
