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 کاملSpatial Mapping of Time-Variable Errors in Jason-1 and TOPEX/Poseidon Sea Surface Height Measurements
Fitting ocean models to altimeter sea surface height (SSH) measurements requires knowledge of instrument noise (radar noise, sea state bias, path delay corrections, and orbit errors) and “representation” errors related to SSH signals (e.g., tidal or pressure driven) not computed in the models. Comparisons between the independent Ocean Topography Experiment (TOPEX)/Poseidon and Jason-1 altimetri...
متن کاملThe Ocean and Climate: Results from the TOPEX/POSEIDON Mission
The ocean circulation and its fluctuations are known to have important consequences for climate variations. It is believed that the datively rapid swings of global temperatures (over 10 degree change in less than 30-50 years) in the past interglacial period is primarily associated with changes in the global ocean circulation which regulates the transport of water, heat, and carbon dioxide in th...
متن کاملSouth China Sea Surface Elevation Variability Determined From TOPEX / POSEIDON Data
1. Introduction The South China Sea (SCS) is a semi-enclosed tropical and subtropical sea located between the Asian land mass (including Taiwan) to the west and north, the Phillipine Islands to the east and Malaysia and Borneo to the south (Figure 1), a total of 3.5×10 6 km 2 surface area. It includes the shallow Gulf of Thailand and connections to the East China Sea (through the Taiwan Strait)...
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...
