Tawhiri 0.1.0

High Altitude Balloon Landing Prediction Software

Package Documentation

Latest Version: 0.2.0


Tawhiri is the name given to the next version of the CUSF Landing Prediction Software, which will probably be different enough from the current version (see below) to warrant a new name.

The name comes from a Māori god of weather, which rather aptly “drove Tangaroa and his progeny into the sea ” (WP).

More information

Please see the CUSF wiki, which contains pages on Tawhiri and prediction in general.


pygrib (at the time of writing) had a broken, so we need to install numpy first, and pyproj separately.

$ sudo aptitude install libevent-dev libgrib-api-dev
$ virtualenv venv
$ source venv/bin/activate
$ pip install numpy
$ pip install pygrib pyproj 'gevent<1.0'

Building the Cython extension
