Description:
tappy 1.2.0
TAPPY is a tidal analysis package. It breaks down a record of water
levels into the component sine waves. It is written in Python and uses
the least squares optimization and other functions in
SciPy. The focus is to make the most accurate
analysis possible. TAPPY only determines the constituents that are
calculable according to the length of the time series.
Features
Outputs a ‘International Hydrographic Organization - Tidal and Water
Level Working Group’ standard XML constituent file.
Uses the IHO standard XML constituent file to make a predicted time
series. By far the most frequent request that I get.
Calculates the node factor at each water elevation measurement. Very
important for long time-series (greater than a year).
Very accurate ephemeris calculations thanks to the
Astrolabe library.
Able to read in different input data sets without changing TAPPY or
the input data set. All you have to do is create a file that defines
the input data set. Thanks to
Pyparsing.
Added the capability to read compressed files and Internet data
streams (actually any URL) directly into TAPPY by using
filelike.
The time-series does not need to have equal intervals. In fact any
length of missing data is allowed (though too much missing will cause
a poor analysis).
Can adjust the Rayleigh factor that nearby constituents are compared
against to determine what constituents can be differentiated.
TAPPY chooses the main constituents based upon the length of the time
series and infers additional constituents that are known to be
specifically related to the main constituents.
Can filter the tidal energy out of the input signal using transform
(FFT), usgs (PL33), doodson, and boxcar methods. |
[CompareTidalFilters]
Can use the tidal filters to zero the time-series before
determination of tidal constituents.
Can pad the usgs, doodson, and boxcar filters with predicted data to
minimize edge effects of the filters.
Convenience function to fill missing values with the predicted time series
Requirements
Python version 3.7.1 or later
SciPy
