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).

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

…is written for Python 3, is compatible with Python 2, and needs Cython:

$ virtualenv venv
$ source venv/bin/activate
$ pip install cython
$ python setup.py build_ext --inplace

The last line (re-)builds the Cython extensions, and needs to be run again after modifying any .pyx files.

The downloader uses gevent, so we are disappointingly restricted to running it under Python 2 for now (Issue #18).

At the time of writing, pygrib head did not work (in contrast to an earlier version; see Issue #15), and both have a broken setup.py. Therefore, we need to install numpy first, and pyproj separately:

$ sudo aptitude install libevent-dev libgrib-api-dev
$ virtualenv -p python2 venv
$ source venv/bin/activate
$ pip install numpy
$ pip install pygrib==1.9.6 pyproj 'gevent<1.0'
