PyGTide v0.5

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 library 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 Anaconda for Python 3+ (Windows 7/10 64bit or Linux (Ubuntu) 64bit)
• Use the Anaconda Navigator to ensure that the following standard libraries are installed: numpy, pandas, datetime and astropy.
• Download PyGTide, unzip into a local directory and run test_pygtide_waves-all.py

The module was compiled for Windows 7/10 and Linux (Ubuntu) and the Python versions 3.5, 3.6, 3.7 and 3.8 (64bit).
