obsarray: Measurement data handling in Python

obsarray is an extension to xarray to support defining, storing and interfacing with measurement data - in particular, measurement uncertainty information using standardised metadata. It is designed to work well with netCDF files and for the Earth Observation community.

obsarray is part of the CoMet Toolkit (community metrology toolkit), and can combined with the punpy (propagating uncertainties in python) module for very simple propagation of defined data uncertainties through arbitrary python functions.
