Sentences with phrase «combined sea level data»

Not exact matches

Even when there doesn't happen to be an overpass at surge time, the statistics of sea level that we got from more than 20 years of repeated altimetric observations in the area can still be combined with data from nearby tide gauges to improve the forecasts of the expected surge.»

Insights into sea level changes, combined with archaeological data on the history of the island's fauna through excavation, has never been done before in charting Zanzibar's history.

The scientists then combined the ancient sea - level data with modern sea - level measurements.

While previous studies had examined the effects of El Niño on sea levels, namely around Australia, this one was the first to look at the U.S. and combine tide gauge and satellite 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.

Personally I think the approach taken by Church and White (2006, 2011) probably comes closest to the true global average sea level, due to the method they used to combine the tide gauge data.

The Arctic altimeter data were retracked using an OCOG retracking algorithm, and the diffuse returns from the leads and open ocean were combined with a host of instrumental corrections and geophysical models to determine instantaneous mean sea level....»

The GRACE observations over Antarctica suggest a near - zero change due to combined ice and solid earth mass redistribution; the magnitude of our GIA correction is substantially smaller than previous models have suggested and hence we produce a systematically lower estimate of ice mass change from GRACE data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged sea level change, or about 6 % of the sea - level change during that period.

An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.

The tide gauges combined with co-located GPS receivers are more accurate (real data) and produces a value around 1.3 to 1.8 mms / year of sea level rise over about 150 sites across the world.

Combined with the altimeter data you should be able to back out the component of sea level rise associated with thermal expansion.

Individual observations combine into very strong evidence that the oceans are gaining heat: 1) ARGO data 2) Sea level data (rising too fast to explain without a thermal component) 3) CO2 rise — yes the heating is expected.

The sea level rise data combined with the Argo data combined with the glacial mass loss estimates provide a pretty strong triangulation of continued gain of energy in the climate system with the majority going to OHC gain since 2003.
