Unified Tidal Analysis and Prediction
Using the ďUTideĒ
- Designed specifically
to handle record times that are irregularly distributed and/or
- 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 process.
- Handles sea level
(amplitude and phase), or currents (current ellipse
parameters), with similar syntax.
- 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
- Enables analysis of
groups of time sequences (such as records from an array of
instruments, or from a group of model gridpoints)
with one m-function call.
- 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.
