MetPy is a collection of tools in Python for reading, visualizing, and performing calculations with weather data.

MetPy is still in an early stage of development, and as such no APIs are considered stable. While we won’t break things just for fun, many things may still change as we work through design issues.

We support Python 2.7 as well as Python >= 3.3.
