Sea Level Changes Along Global Coasts from Satellite Altimetry, GPS and Tide Gauge
The average global sea level was rising through the 20th century as a result of global warming [8, 9, 26]. The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) estimated that between 1901 and 2010, the mean sea level rate 1.7±0.2 mm/yr and increased to 3.2±0.4 mm/yr between 1993 and 2010, and projected that in 2100 the largest increase in global average sea level ...
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 کاملMonitoring sea level change at Cascais tide gauge
Sea level change (SLC) real-time monitoring has being developed and improved for the Portuguese tide gauge, based in FTP access to the internet server of the Portuguese geographical institute. A software application, named MareVB and in development since 2008, gets a 3 minute stream input of sea level height and a 10 minute stream input of air-pressure. Based on a predicted tide model, the sea ...
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 کاملGravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines
Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...
