filehandler Module

class metrics.filehandler.FileHandler

Simple static class to read and write netcdf files unsing scipy.io.netcdf

static createDimension(f, value, name, var_type='double')

Create a dimension in netcdf file f

Parameters:

• f – open netcdf file
• value – array or list with dimenstion data
• name – name of dimension
• var_type – type of dimenstion (double, float, ...)

static _copyNetCDF(fn, new_fn, field)

Copies a given netcdf file using scipy.io Also stores a new field in the netcdf file

Parameters:

• fn – filename of netcdf to copy
• new_fn – new filename
• field – Array with new values for result file

static saveToNetCDF(field, refFile, tag)

Saves a numpy array to an netCDF file.

Parameters:

• field – numpy array
• refFile – File to “clone”
• tag – new filename

:return filepath

static getVariableValue(var)

Get values of a variable using scipy.io

Parameters:var – netcdf.variable

static openNetCDFFile(fn, mode='all')

Open a file as numpy array Either get a dict with “var”,”lon”,”lat” or only “var” New Option mode=’plev’ gives also pressure levels
