The linear response function technique is used to analyze two 1300-km tracks of SEASAT altimeter data and corresponding bathymetry in the Musician Seamounts region north of Hawaii. Bathymetry and geoid height are highly correlated in the 50to 300-km wavelength range. A predictive filter is developed which can operate on SEASAT altimetry in poorly surveyed oceanic regions to indicate the presenc...

Mapping the mesoscale surface velocity stream function by combining estimates of surface height from satellite altimetry and surface currents from sequential infrared (sea-surface temperature) imagery using optimal interpolation is described. Surface currents are computed from infrared images by the method of maximum crosscorrelations (MCC) and are combined with altimeter sealevel anomaly data ...

M easurements of topography can provide a wealth of information on landscape properties fw managing hydrologic and geologic systems and conserving natural and agricultural resources. This article discusses the application of an airborne laser altimeter to measure topography and other landscape surface properties. The airborne laser altimeter makes 4000 measurements per second with a vertical re...

Microwave radiometers form an integral part of satellite altimetry. The long-term stability of the radiometer measurements is as important to the accurate determination of sea level rise as is the long-term stability of the altimeter instrument. However, the radiometer stability has been largely taken for granted. Detailed long-term study of the brightness temperatures of ERS-1, ERS-2, TOPEX/Po...

Since some time several altimeter satellites are operating simultaneously (ENVISAT, Jason-1, ERS-2, GFO, TOPEX/Poseidon). The large number of nearly simultaneous crossover events are used to estimate in a common adjustment radial error components of all altimeter missions. A discrete representation is used for the radial error components by minimizing both, crossover differences and consecutive...

[1] A merged TOPEX/POSEIDON and ERS-1/2 altimeter data set is used to estimate nonseasonal variations of sea surface height (SSH) in the Japan/East Sea (JES) from October 1992 through February 2002. The altimeter data have a good correlation (0.95) with tide gauge data in the western JES. The nonseasonal variability of the SSH is higher in the southern warm region than in the northern cold regi...

The usability of altimeter sea level data (TOPEX/POSEIDON) and scatterometer wind data (QuikSCAT) in El Niño and the Southern Oscillation (ENSO) prediction is investigated with the latest version of the Lamont forecast model. The emphasis of this study is on the effectiveness of these data sets in initializing the model to forecast the 1999–2000 La Niña conditions. Both the altimeter and scatte...
