Vertical Motion determined using Satellite Altimetry and tide Gauges
A robust method to estimate vertical crustal motions by combining geocentric sea level measurements from decadal (1992 2003) TOPEX/POSEIDON satellite altimetry and long-term (> 40 years) relative sea level records from tide gauges using a novel Gauss-Markov stochastic adjustment model is presented. These results represent an improvement over a prior study (Kuo et al. 2004) in Fennoscandia, wher...
متن کاملSea Level Determination Experiences at Cape of Begur Using Altimetry and Tide Gauges
Three Begur Cape experiences on radar altimeter calibration and marine geoid mapping made on 1999, 2000 and 2002 are overviewed. The marine geoid has been used to relate the coastal tide gauge data from l’Estartit harbour to off-shore altimetric data. The necessity to validate and calibrate the satellite’s altimeter due to increasing needs in accuracy and long term integrity implies establishin...
متن کاملReply to Kennedy et al.: Katrina storm records in tide gauges.
We appreciate the opportunity to discuss our definition of events of Katrina magnitude. Kennedy et al. (1) argue that our definition of Katrina magnitude events (2) is too low because we do not use any tide gauge data in the immediate proximity of New Orleans and the region of absolute maximal surge height. We note that hurricane best track records (3) for Katrina magnitude events show a ~20-y ...
متن کاملMonitoring Sea Level in the Coastal Zone with Satellite Altimetry and Tide Gauges
We examine the issue of sustained measurements of sea level in the coastal zone, first by summarizing the long-term observations from tide gauges, then showing how those are now complemented by improved satellite altimetry products in the coastal ocean. We present some of the progresses in coastal altimetry, both from dedicated reprocessing of the radar waveforms and from the development of imp...
متن کاملThe M4 Shallow Water Tidal Constituent From Altimetry and Tide Gauges
Present global ocean tide models based on the TOPEX/POSEIDON satellite data are still not accurate enough on the continental shelves for detailed oceanographic studies. The need for increasing accuracy in shelf regions calls for inclusion of more than just semidiurnal and diurnal constituents in future global ocean tide models. This study is an extension to previous investigations on the Northw...
