SkewTplus – Atmospheric Profile Plotting and Diagnostics¶
The SkewTplus package provides tools to easily read atmospheric sounding data from different formats (University of Wyoming and ARM) and create SkewT sounding plots along with parcel diagnostics (CAPE,CIN,etc.).
This package is based on the SkewT Python package developed by Thomas Chubb (https://pypi.python.org/pypi/SkewT/)
The main difference with the original SkewT package is that the vertical soundings plots are handled by a special class (SkewT). The new SkewT class extends the base matplolib’s Figure class with an interface similar to matplolib’s pyplot. It also allows to create Skew-T type plots in a simple way. This new class allows a complete control over the Figure properties like multiple plots (normal axis and Skew-T axis).
In addition, the thermodynamics module was improved. All the intensive computations were migrated to Cython and parallelized.
The SkewT Python package was a cornerstone of this project. We are grateful to all its collaborators.

Installing SkewTplus¶
IMPORTANT - OSX installation¶
Before installing the package, be sure that Numpy is installed. Then, install the apple’s Xcode application by running:
xcode-select --install
Before running the pip or the setup commands execute:
export CC=clang ; export CXX=clang
Then you can continue with any of the following installation procedures.
Nevertheless pip is highly recommended.
PIP install¶
To install the package using pip the numpy package must be already installed. If is not installed, you can install it by running:
pip install numpy
After the numpy package was installed, to install the SkewTplus package run:
pip install SkewTplus
Install from source¶
The latest version can be installed manually by downloading the sources from https://github.com/aperezhortal/SkewTplus
To install the package manually, the numpy package must be already installed. If is not installed, you can install it by running:
pip install numpy
Then, you can install the SkewTplus package executing:
python setup.py install
If you want to put it somewhere different than your system files, you can do:
python setup.py install --prefix=/path/to/local/dir
IMPORTANT: If you install it using this way, all the dependencies need to be already installed!
Conda install - Only available linux users¶
If you are using an anaconda environment, to install the package execute:
conda install -c andresperezcba skewtplus
