Tawhiri 0.1.0

High Altitude Balloon Landing Prediction Software

Package Documentation


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
