Python package to simplify working with gridded data

njord

A package to generalize and simplify working with different types of geophysical/oceanographical/meterological data. The package allows for analysis and presentation of data from different sources in a unified way and provides a number of functions for this. The package requires some work to when first setup, both by editing the config file and most likely adding modules/classes.

The structure is as follows:

A class represents a specific dataset. A module contains all classes from the same source. They are normally setup in the same format.

Installation

• (Edit config file and add modules/classes.)
• sudo python setup.py install # global installation
• python setup.py install --user # installation for current user

Define a project in one of the following files:

./njord.cfg ~/.njord.cfg /path/to/package/njord.cfg

Example:

[Default]
basedir:     /projData

[rutgers.Coral]
datadir:     %(basedir)s/rutgers/CORAL/
gridfile:    %(datadir)s/coral_grd.nc
map_region:  indthr
imt:         1281
jmt:         641

Usage

>>> from njord import rutgers 
>>>
>>> #Create a grid instance
>>> mp = rutgers.Coral('handle')
>>>
>>> #Load u-velociites
>>> mp.load('u')
