Install

pyPSCF is written in python 3 so the first thing to do is to… well, install python.

• Linux: it should be already installed. However, depending on your distribution, you may have python 2 by default. We do not ensure the compatibility.

• Windows/macOS: just use python throught anaconda. It’s way more easier. But use anaconda for python 3.

Hysplit

The GUI has the ability to compute HYSPLIT backtrajectories. To do so, you will need Hysplit installed.

Hysplit is freely available for Windows, Linux and Mac on the NOAA website.

You may also need the NCEP reanalyse GDAS, available in by the NOAA.

pyPSCF

Install latest release version via pip

pip install pyPSCF

Install latest release version via conda

conda install -c webersa pypscf

Mannual install (not recommanded)

pyPSCF use the following library:

• matplotlib

• numpy

• scipy

• pandas

• cartopy

The first fourth are quite heavily used and easy to install (or already installed). You can use pip to install them:

pip install matplotlib numpy scipy pandas

Cartopy is a bit tricky to install as it requires an extra library: GEOS. In debian related system, install it via:

sudo apt install libgeos-3.6.2 libgeos++-dev

Due to some cartopy related issue, you may also need cython. Install it via conda or pip such as:

pip install cython
pip install cartopy
