The effects of rain on TOPEX/Poseidon altimeter data
The presence of rain in the sub-satellite track can significantly degrade altimeter measurements by causing an attenuation of the backscattered signal, a change in its path length through the atmosphere and a change in the mean square slope of the sea surface. This can cause errors, not only in the measurement of the satellite altitude, but also in the determination of wind speed and wave heigh...
متن کاملA comparison of ocean topography derived from the Shuttle Laser Altimeter-01 and TOPEX/POSEIDON
To assess the utility of laser altimetry for studies in dynamical oceanography, we present a comparison of the Shuttle Laser Altimeter (SLA)-01 and the TOPEX/POSEIDON (T/P) radar altimeter on global and regional scales. We compare all 1.1 million SLA-01 range measurements over the oceans to the CSRMSS95 gridded mean sea surface model and find the overall root mean square (RMS) difference to be ...
متن کاملTopex/Poseidon Satellite Altimetry
A recently developed multiresolution estimation framework offers the possibility of highly efficient statistical analysis, interpolation, and smoothing of extremely large data sets in a multiscale fashion. This framework enjoys a number of advantages not shared by other statistically-based methods. In particular, the algorithms resulting from this framework have complexity that scales only line...
متن کاملEstimating terrestrial snow depth with the TOPEX-Poseidon altimeter and radiometer
Active and passive microwave measurements obtained by the dual-frequency Topex–Poseidon radar altimeter from the Northern Great Plains of the United States are used to develop a snow pack radar backscatter model. The model results are compared with daily time series of surface snow observations made by the U.S. National Weather Service. The model results show that Ku-band provides more accurate...
متن کاملValidation of Wavewatch-III Using the TOPEX/POSEIDON Data
A full-spectral third-generation ocean wind-wave model, Wavewatch-III, has been implemented in the South China Sea (SCS) for investigating the wind wave characteristics. This model was developed at the Ocean Modeling Branch of the National Centers for Environmental Prediction (NCEP). The NASA QuickScat data (0.25 resolution) two times daily were used to simulate the wind waves for the whole yea...
