Bases: gnome.environment.environment.Environment

todo: baseclass called ScaleTimeseries (or something like that) ScaleCurrent Define the tide for a spill

Currently, this internally defines and uses the CyShioTime object, which is a cython wrapper around the C++ Shio object

Tide information can be obtained from a filename or set as a timeseries (timeseries is NOT TESTED YET)

It requires one of the following to initialize:

  1. ‘timeseries’ assumed to be in ‘uv’ format (NOT TESTED/IMPLEMENTED OR USED YET)

  2. a ‘filename’ containing a header that defines units amongst other meta data

Parameters:

  • timeseries (numpy.ndarray with dtype=datetime_value_1d) – numpy array containing tide data

  • units – units associated with the timeseries data. If ‘filename’ is given, then units are read in from the filename. unit conversion - NOT IMPLEMENTED YET

  • filename – path to a long wind filename from which to read wind data

  • yeardata='gnome/data/yeardata/' – path to yeardata used for Shio data.
