atmosp 0.2.13

Atmospheric sciences utility library

atmos is a library of Python programming utilities for the atmospheric sciences. It is in ongoing development. If you have an idea for a feature or have found a bug, please post it on the GitHub issue tracker.

Information on how to use the module can be found predominantly by using the built-in help() function in Python. Many docstrings are automatically generated by the module and so information may appear to be missing in the source code. There is also HTML documentation available.

This module is currently alpha. The API of components at the base module level should stay backwards-compatible, but sub-modules are subject to change. In particular, features in the util module are likely to be changed or removed entirely.
