Aliased tidal errors in TOPEX/POSEIDON sea surface height data

Creator:: Schlax, Michael G. and Chelton, Dudley B.
Abstract:: Alias periods and wavelengths for the M2, S2, N2, K1, O1, and P1 tidal constituents are calculated for TOPEX/POSEIDON. Alias wavelengths calculated in previous studies are shown to be in error, and a correct method is presented. With the exception of the K1 constituent, all of these tidal aliases for...

Detecting aliased tidal errors in altimeter height measurements

Creator:: Schlax, Michael G. and Chelton, Dudley B.
Abstract:: A simple statistic is derived for quantifying the potential for the aliasing of tidal errors in a given linear estimate of sea surface height constructed from altimeter data. The existence of M2 tidal constituent errors in Geosat data processed in the traditional way (i.e., with orbit errors removed using least...

The influence of mesoscale eddies on the detection of quasi-zonal jets in the ocean

Creator:: Schlax, Michael G. and Chelton, Dudley B.
Abstract:: Westward propagating Gaussian eddies with statistical characteristics estimated from altimeter observations but with purely random starting locations and times produce striated features in time-averaged maps of zonal velocity. The striations in these simulations have magnitudes and meridional scales comparable to those reported from time-averaged altimeter observations and model output in...

The Accuracies of Smoothed Sea Surface Height Fields Constructed from Tandem Satellite Altimeter Datasets

Creator:: Chelton, Dudley B. and Schlax, Michael G.
Abstract:: A technique previously developed for assessing the effects of sampling errors on sea surface height (SSH) fields constructed from satellite altimeter data is extended to include measurement errors, thus providing estimates of the total mean-squared error of the SSH fields. The measurement error contribution becomes an important consideration with the...

The Accuracies of Crossover and Parallel-Track Estimates of Geostrophic Velocity from TOPEX/Poseidon and Jason Altimeter Data

Creator:: Schlax, Michael G. and Chelton, Dudley B.
Abstract:: Mean-squared errors of surface geostrophic velocity estimates from the crossover and parallel-track methods are calculated for altimeters in the Ocean Topography Experiment (TOPEX)/Poseidon and Jason orbits. As part of the crossover method analysis, the filtering properties and errors of cross-track speed estimates are examined. Velocity estimates from both the crossover...

Randomness, Symmetry, and Scaling of Mesoscale Eddy Life Cycles

Creator:: Samelson, R. M., Schlax, M. G., and Chelton, D. B.
Abstract:: It is shown that the life cycles of nonlinear mesoscale eddies, a major component of low-frequency ocean physical variability, have a characteristic structure that differs fundamentally from that which would be expected on the basis of classical interpretations of ocean eddy evolution in terms of mean flow instability and equilibration...

Summertime Coupling between Sea Surface Temperature and Wind Stress in the California Current System

Creator:: Chelton, Dudley B., Schlax, Michael G., and Samelson, Roger M.
Abstract:: Satellite observations of wind stress and sea surface temperature (SST) are analyzed to investigate ocean–atmosphere interaction in the California Current System (CCS). As in regions of strong SST fronts elsewhere in the World Ocean, SST in the CCS region is positively correlated with surface wind stress when SST fronts are...

The Midlatitude Resolution Capability of Sea Level Fields Constructed from Single and Multiple Satellite Altimeter Datasets

Creator:: Greenslade, Diana J. M., Chelton, Dudley B., and Schlax, Michael G.
Abstract:: A formalism recently developed for determining the effects of sampling errors on objectively smoothed fields constructed from an irregularly sampled dataset is applied to investigate the relative merits of single and multiple satellite altimeter missions. For small smoothing parameters, the expected squared error of smoothed fields of sea surface height...

Estimation of Time Averages from Irregularly Spaced Observations: With Application to Coastal Zone Color Scanner Estimates of Chlorophyll Concentration

Creator:: Chelton, Dudley B. and Schlax, Michael C.
Abstract:: A formalism is presented for quantifying the sampling error of an arbitrary linear estimate of a time-averaged quantity constructed from a time series of irregularly spaced observations at a fixed location. The method is applicable to any irregularly sampled time series; it is applied here to satellite observations of chlorophyll...
