TSPROC is a Time Series PROCessor that uses a configuration file to describe the tasks the data scientest or modeler wants to accomplish. TSPROC was initially developed by John Doherty as part of the ‘Surface Water Utilities’ to support the use of his Parameter ESTimation (PEST) suite of optimization programs. Even though there are important components in TSPROC that are only used with PEST, TSPROC has general utility outside the PEST environment. I am involved in the ‘next-generation’ TSPROC development headed up by Steve Westenbroek of the Wisconsin USGS.

Tidal Analysis Program in Python. Takes a time-series of water level observations and finds the pure sine wave tidal constituents that would sum to the observations. TAPPy can then take the calculated constituents and make predictions of tidal heights in the future.

I have been planning a rewrite of TAPPy, but that will probably take a while. In the meantime, there are new tidal analysis tools written using Python which might be better/easier to use than TAPPy. Check out in no particular order;

With things always moving, if the OSU work can get you what you need, why do tidal analysis at all?
