CTyPyTool: Cloud Typing Python Tool

This tools is intended to help weather forecasters in assessing the quality of their cloud forecasts.

A few facts:

• It emulates a cloud typing methodology (see https://www.nwcsaf.org/ct2) applied to Meteosat data (see https://www.eumetsat.int/meteosat-second-generation).
• It uses standard machine learning techniques, e.g. tree & random forest classifier
• It can be applied to so-called synthetic satellite data (observsation-equivalents derived from numerical forecast data).

Getting Started

There are severeal Jupyter Notebooks explaining the basic steps for training and applying the cloud classifier.

For using an already trained classifier check out this notebook
