Reconstruction of past decades sea level using thermosteric sea level, tide gauge, satellite altimetry and ocean reanalysis data.

In a second step, we apply the method to reconstructing 2 - D sea level data over 1950 — 2003, combining sparse tide gauge records available since 1950, with EOF spatial patterns from different sources: (1) thermosteric sea level grids over 1955 — 2003, (2) sea level grids from Topex / Poseidon satellite altimetry over 1993 — 2003, and (3) dynamic height grids from the SODA reanalysis over 1958 — 2001.

A group of people analyzing sea level data points from satellite altimetry, where the errors inherent in the methodology are greater than the absolute trend itself and all sorts of adjustments must be made to get anything out of the raw data, are in much worse shape than the guy making the mark in stone.

Likewise, Cazenave 2014 had published according to altimetry data, sea level had decelerated from 3.5 mm / yr in the 1990s to 2.5 mm / yr during 2003 - 2011, and that deceleration could be explained by increased terrestrial water storage, and the pause in ocean warming reported by Argo data.

The long - term tide gauges in the Mediterranean show sea - level trends for the 20th century in the range of 1.1 — 1.3 mm / yr whilst more recent satellite altimetry data reveals much larger increases in sea - level throughout the basin towards the latter part of the century.

It is regrettable that the Colorado folks are unaccountably late with the latest tranche of JASON sea - level data... for the next decade the satellite sea - level altimetry data, the ice - mass gravimetry data, and the ARGO ocean - temperature, all will (quite rightly) be a key focus of scientific attention.

«Here we present an analysis based on sea - level data from the altimetry record of the past ~ 20 years that separates interannual natural variability in sea level from the longer - term change probably related to anthropogenic global warming... Our results confirm the need for quantifying and further removing from the climate records the short - term natural climate variability if one wants to extract the global warming signal.»

Analyses of tide gauge and altimetry data by Vinogradov and Ponte (2011), which indicated the presence of considerably small spatial scale variability in annual mean sea level over many coastal regions, are an important factor for understanding the uncertainties in regional sea - level simulations and projections at sub-decadal time scales in coarse - resolution climate models that are also discussed in Chapter 13.

Accounting for the TOPEX - A instrumental correction for the first 6 years of the altimetry data set, these studies provided a revised global mean sea level time series that slightly reduces the average GMSL rise over the altimetry era (from 3.3 mm / yr to 3.0 mm / yr) but shows clear acceleration over 1993 - present.

Is there any altimetry data to show how mean sea level varies along the peruviean coast during these events?

Different approaches have been used to compute the mean rate of 20th century global mean sea level (GMSL) rise from the available tide gauge data: computing average rates from only very long, nearly continuous records; using more numerous but shorter records and filters to separate nonlinear trends from decadal - scale quasi-periodic variability; neural network methods; computing regional sea level for specific basins then averaging; or projecting tide gauge records onto empirical orthogonal functions (EOFs) computed from modern altimetry or EOFs from ocean models.
