The PO.DAAC is pleased to announce the release of the Reconstructed Sea Level
Anomaly Dataset
The Reconstructed Sea Level Anomaly dataset contains Sea Level Anomalies
derived from satellite altimetry and tide gauges. It spans from January
3, 1950 to June 27, 2009. The reconstructed fields are obtained by
fitting satellite altimetry-derived basis functions, computed using
cyclostationary empirical orthogonal functions (CSEOF), to historical tide
gauge data. The result is a dataset with the spatial resolution of the
satellite altimetry and the record length of the tide gauges. For
specific information on the algorithm and how the CSEOFs are applied to the
tide gauge data please see Hamlington, B. D., R. R. Leben, R. S. Nerem, W.
Han, and K.-Y. Kim (2011), Reconstructing sea level using cyclostationary
empirical orthogonal functions, Journal of Geophysical Research, 116, C12015,
doi:10.1029/2011JC007529.
The data are provided on 0.5 degree grids with a 7 day temporal
resolution. The data are in NetCDF, and each file contains
approximately 10 years worth of data. There will be periodic updates
that will extend the time series.
The dataset highlight page (http://podaac.jpl.nasa.gov/highlights/ReconstructedSeaLevelDataset_2013_0617) contains
example figures and cursory information about the data.
