PyGTide
A Python module and wrapper for ETERNA PREDICT to compute gravitational tides on Earth
PyGTide is a Python class that wraps around ETERNA PREDICT 3.4 which was compiled from Fortran into a Python DLL using f2py. The original ETERNA PREDICT 3.3 was written by the late Prof. H.-G. Wenzel (Wenzel, 1996) in a mix of Fortran 77 and 90. This was updated by Kudryavtsev (2004) to include the latest tidal catalogue. The Fortran code for ETERNA PREDICT can be downloaded from the International Geodynamics and Earth Tide Service (IGETS).
How to install and run
A user guide is available as PDF download.
Instructions:
- Download and install Anaconda3 5.2 for Python 3.6 (Windows 7/10 64bit)
- Use the Anaconda Navigator to ensure that the packages libpython (as a minimum v2.1) and mingw (as a minimum v4.7) are installed. You will also need the following standard libraries: numpy, pandas and datetime.
- Download PyGTide, unzip into a local directory and run test.py
