Atlite with improvements allowing to download and use CMIP6 models within Atlite

This branch was created for the purpose of ananlyzing effects of climate change in the end of century on wind and solar energy. For this purpose, CMIP6 climate models were used within Atlite, therefore, some improvements within Atlite had to be made. The full work is briefly described in the commit descriptions. Main improvements include:

• Ability to use CMIP6 models
• Use of multiple temporal frequencies for climate model variables
• Use of multiple wind speed height levels used to calculate wind speed at hub height (based on power law)
• Calculation of capacity factors per cell (without performing aggregation)

The documentation below is retrevied from the main branch of Atlite.

Atlite

Atlite is a free software, xarray-based Python library for converting weather data (like wind speeds, solar influx) into energy systems data. It has a lightweight design and works with big weather datasets while keeping the resource requirements especially on CPU and RAM resources low.

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.
