Global Mean Sea Level. Time Trends and Persistence with Long Range Dependent Data
نویسندگان
چکیده
Global mean sea level data are examined in this work by looking at the presence of time trends context long memory or range dependent processes. By both seasonal signals retained and removed from 1992 to 2020, results show that two series display significant trend coefficients high levels persistence.

Trends in UK Mean Sea Level Revisited
This paper presents estimates of rates of mean sea level (MSL) change around the UK based on a larger tide gauge data set and more accurate analysis methods than have been employed so far. The spatial variation of the trend in MSL is found to be similar to that inferred from geological information and from advanced geodetic techniques, which is a similar conclusion to that arrived at in previou...
متن کاملHybrid Decade-mean Global Sea Level
Improved global mean sea level is obtained by combining two datasets: large-scale mean sea level based on measurements of twin-satellite mission GRACE and mesoscale sea level tilt derived from the momentum balance as seen in drifter, satellite altimeter and wind data. Hybrid product reveals complex structures of main currents even after averaging over 10 years and shows their places in the larg...
متن کاملGlobal Sea Surface Temperature and Sea Level Rise Estimation with Optimal Historical Time Lag Data
Prediction of global temperatures and sea level rise (SLR) is important for sustainable development planning of coastal regions of the world and the health and safety of communities living in these regions. In this study, climate change effects on sea level rise is investigated using a dynamic system model (DSM) with time lag on historical input data. A time-invariant (TI-DSM) and time-variant ...

متن کاملAre Long Tide Gauge Records in the Wrong Place to Measure Global Mean Sea Level Rise?
Ocean dynamics, land motion, and changes in Earth’s gravitational and rotational fields cause local sea level change to deviate from the rate of global mean sea level rise. Here we use observations and simulations of spatial structure in sea level change to estimate the likelihood that these processes cause sea level trends in the longest and highest-quality tide gauge records to be systematica...
