Empirical Ocean Tide Model (EOT)

DGFI-TUM's empirical ocean tide models are global solutions providing amplitudes and phases of the most dominant ocean tide constituents based on an empirical analysis of multi-mission satellite altimetry data. The models were obtained by means of residual harmonic analysis of multi-mission altimeter data with respect to FES2004 (Lyard et al, 2006). The most recent model is EOT11a.

Ocean tide corrections and ocean load tide corrections from EOT11a are provided along-track for all available satellite altimeter missions. The EOT11a model itself (grids for different tide constituents) is available via PANGAEA (http://doi.pangaea.de/10.1594/PANGAEA.834232).

Available Dataset(s)

Available version(s) of the product "Empirical Ocean Tide Model (EOT)" in OpenADB.

The EOT models are distributed in the hope that they will be useful, but DGFI-TUM provides EOT models "as is" without warranty, expressed or implied, as to the use or appropriateness of the EOT ocean tide models, and there are no warranties of merchantability or fitness for a particular purpose or use.

Data Format

The product "Empirical Ocean Tides (EOT)" includes the following parameters.

Parameter	Description
glon	Longitude of Satellite Footprint
glat	Latitude of Satellite Footprint
jday	Julian Day 2000
otide	Ocean Tide Correction
ltide	Ocean Load Tide Correction
oflags	Orbit Status and Quality Flags

The data will be provided in NetCDF. More details on the data are available here.

OpenADB provides EOT models as ocean tide correction (otide) and loading tide correction (ltide) along-track per mission. In addition, gridded files for each constituent (where the tidal constants were stored in complex form, e.g. as cos- and sin-terms) as well as spherical harmonics are provided via FTP.
