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...

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...

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...

Spectral charactersitics of time-dependent orbit errors in altimeter height measurements

Creator:: Chelton, Dudley B. and Schlax, Michael G.
Abstract:: A mean reference surface and time-dependent orbit errors are estimated simultaneously for each exact-repeat ground track from the first two years of Geosat sea level estimates based on the Goddard Earth model (GEM)-T2 orbits. Motivated by orbit theory and empirical analysis of Geosat data, the time-dependent orbit errors are modeled...

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...

Geosat altimeter observations of the surface circulation of the Southern Ocean

Creator:: Chelton, Dudley B., Schlax, Michael G., Witter, Donna L., and Richman, James G.
Abstract:: The variability of sea level and surface geostrophic currents in the Southern Ocean is investigated from the first 26 months of unclassified Geosat altimeter data (November 1986 to December 1988). Because of problems unique to Geosat, it has been necessary to develop new techniques for analyzing the height data. These...

Seasonal variability in the Southwestern Atlantic

Creator:: Matano, Ricardo P., Schlax, Michael G., and Chelton, Dudley B.
Abstract:: The circulation of the southwestern Atlantic Ocean is dominated by the Subtropical Gyre and the confluence of the Brazil and Malvinas currents. Observations indicate that the latitude of this confluence changes seasonally, lying farther north during the austral winter than during the summer. This phenomenon has important consequences for the...

Geographical Variability of the First Baroclinic Rossby Radius of Deformation

Creator:: Chelton, Dudley B., deSzoeke, Roland A., Schlax, Michael G., El Naggar, Karim, and Siwertz, Nicolas
Abstract:: Global 1° × 1° climatologies of the first baroclinic gravity-wave phase speed c¹ and the Rossby radius of deformation λ1 are computed from climatological average temperature and salinity profiles. These new atlases are compared with previously published 5° × 5° coarse resolution maps of λ₁ for the Northern Hemisphere and...

Diagnosis of the Three-Dimensional Circulation Associated with Mesoscale Motion in the California Current

Creator:: Shearman, R. Kipp, Barth, John A., and Kosro, P. Michael
Abstract:: A high-resolution upper-ocean survey of a cyclonic jet meander and an adjacent cyclonic eddy in the California Current region near 38°N, 126°W was conducted as part of the summer of 1993 Eastern Boundary Currents program. Temperature and salinity were measured from a SeaSoar vehicle, and velocity was measured by shipboard...
