Retrieving Data

Not all data dependencies are shipped with the git repository, since git is not suited for handling large changing files. Instead we provide separate data bundles which can be obtained using the retrieve* rules.

Rule retrieve_databundle

The data bundle (1.4 GB) contains common GIS datasets like NUTS3 shapes, EEZ shapes, CORINE Landcover, Natura 2000 and also electricity specific summary statistics like historic per country yearly totals of hydro generation, GDP and POP on NUTS3 levels and per-country load time-series.

This rule downloads the data bundle from zenodo and extracts it in the data sub-directory, such that all files of the bundle are stored in the data/bundle subdirectory.

The Tutorial: Electricity-Only uses a smaller data bundle than required for the full model (188 MB)

Outputs

• data/bundle: input data collected from various sources

Rule retrieve_cutout

Cutouts are spatio-temporal subsets of the European weather data from the ECMWF ERA5 reanalysis dataset and the CMSAF SARAH-2 solar surface radiation dataset for the year 2013. They have been prepared by and are for use with the atlite tool. You can either generate them yourself using the build_cutouts rule or retrieve them directly from zenodo through the rule retrieve_cutout. The Tutorial: Electricity-Only uses a smaller cutout than required for the full model (30 MB), which is also automatically downloaded.

Note

To download cutouts yourself from the ECMWF ERA5 you need to set up the CDS API.

Outputs

• cutouts/{cutout}: weather data from either the ERA5 reanalysis weather dataset or SARAH-2 satellite-based historic weather data.

For details see build_cutout and read the atlite documentation.

Rule retrieve_natura_raster

This rule, as a substitute for build_natura_raster, downloads an already rasterized version (natura.tiff) of Natura 2000 natural protection areas to reduce computation times. The file is placed into the resources sub-directory.

Relevant Settings

enable:
    build_natura_raster:

Outputs

• resources/natura.tiff: Rasterized version of Natura 2000 natural protection areas to reduce computation times.

Rule retrieve_electricity_demand

This rule downloads hourly electric load data for each country from the OPSD platform.

Relevant Settings

None.

Outputs

• data/load_raw.csv

Rule retrieve_cost_data

This rule downloads techno-economic assumptions from the technology-data repository.

Rule retrieve_ship_raster

This rule downloads data on global shipping traffic density from the World Bank Data Catalogue.

Relevant Settings

None.

Outputs

• data/shipdensity_global.zip

Rule retrieve_sector_databundle

In addition to the databundle required for electricity-only studies, another databundle is required for modelling sector-coupled systems. The size of this data bundle is around 640 MB.
