Unified Tidal Analysis and Prediction
Using the ďUTideĒ Matlab Functions
specifically to handle record times that are irregularly distributed
- Suitable for
multi-year analyses: accurate nodal/satellite corrections are not limited
to record lengths shorter than 1-2 years.
- Can provide
easy-to-use and comprehensive diagnostics to aid the constituent selection
- Handles sea level
(amplitude and phase), or currents (current ellipse parameters), with
- Generates confidence
intervals based on spectra (FFT for regular times, Lomb-Scargle for irregular times) of the residuals between the
raw input and the harmonic fit.
- Incorporates the
robust L1/L2 solution method to minimize influence of outliers.
- Enables analysis of
groups of time sequences (such as records from an array of instruments, or
from a group of model gridpoints) with one
- Builds on, and
integrates in to a common framework, the t_tide
(Pawlowicz et al 2002), r_t_tide
(Leffler and Jay 2009), and
"versatile" (Foreman et al 2009) approaches.
- Flexible interface
with mix-and-match choices of analysis configurations accessible by
arguments to m-functions.
