A Python library for producing cloud masks of SLSTR scenes using a neural network.

Also includes functions to produce a collocated training data set using either the CALIOP or CATS missions to provide cloud feature labels. In addition, functionality is provided to evaluate the model's performance in different situations using various metrics.

False Colour Image	Neural Network Mask	Bayesian Mask

This library produces cloud masks which are an improvement over the current standard bayesian ESA masks.

After cloning this repository and navigating to its install directory, the dependencies can be installed with anaconda:

conda env create -f environment.yml

This will create a new anaconda environment 'cloud-id'. After activating the environment:

conda activate cloud-id

A toggleable matplotlib figure can be produced for an SLSTR S3A_SL_1_RBT folder at PATH with:

python MaskToggle.py PATH

Valid SLSTR files are available from https://scihub.copernicus.eu/s3/#/home
