 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.

+With `atlite` we want to provide an interface between the meteorological and energy systems modelling communities.
+
+Traditionally the MET and ESM communities have not been interacting much.
+The outputs and learning of one community were only slowly adapted into the other community.
+
+With `atlite` we want bridge between the communities:
+We want to make it easy to use and integrate outputs of the MET communities into energy system models, by offering standardized ways of accessing weather/climate datasets and converting them to weather-dependent inputs for ESMs.

 ===============
-.. * Install atlite from conda-forge or pypi.
-.. * Download one of the weather datasets listed above (ERA5 is downloaded
-..   automatically on-demand after the ECMWF
-..   `cdsapi<https://cds.climate.copernicus.eu/api-how-to>` client is
-..   properly installed)
-.. * Create a cutout, i.e. a geographical rectangle and a selection of
-..   times, e.g. all hours in 2011 and 2012, to narrow down the scope -
-..   see `examples/create_cutout.py <examples/create_cutout.py>`_
-.. * Select a sparse matrix of the geographical points inside the cutout
-..   you want to aggregate for your time series, and pass it to the
-..   appropriate converter function - see `examples/ <examples/>`_
