Atlite is a free software, xarray-based Python library for converting weather data (like wind speeds, solar influx) into energy systems data. It is designed to be lightweight, keeping computing resource requirements (CPU, RAM) usage low. It is therefore well suited to be used with big weather datasets.

Atlite can process the following weather data fields and can convert them into following power-system relevant time series for any subsets of a full weather database.

Atlite was initially developed by the Renewable Energy Group at FIAS to carry out simulations for the CoNDyNet project, financed by the German Federal Ministry for Education and Research (BMBF) as part of the Stromnetze Research Initiative.
