# Downloading and Read RESKit Input Data

RESKit requires input data sources to simulate the respective technologies. To download, inspect and preprocess some of the data some examples are provided in the following 

Examples are provided for 

## Time resolved Weather data

1. ERA5 Dataset https://doi.org/10.24381/cds.adbb2d47. ERA5 is an abbreviation for ECMWF Reanalysis v5, which stands for the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis version 5.

   2.  [Calculate the absolute Windspeeds from the ERA5 data](../../examples/1_load_input_data/1_1_2_wind_speed_from_vectors_in_era5.ipynb)
2. The MERRA Dataset https://doi.org/10.1175/JCLI-D-11-00015.1. Merra stands for Modern Era Retrospective-Analysis for Research and Applications.

   2.  [Calculate Windspeeds from MERRA data](../../examples/1_load_input_data/1_2_2_vertically_project_wind_speed_from_merra.ipynb)
<!-- 3. ICONLAM # TODO Create Example 
1. COSOMO # Needs check for relevance # TODO Create Example -->

<!-- ## Globally spatially Resolved Irrdatioan and Windspeed Data

1. Global Solar Atlas (GSA) # No Example
2. Global Wind Atlas  (GWA) # No Example -->

# Wind Power Curves 
A wind turbine power curve is a chart that shows how much power a turbine generates at various wind speeds.

1. Power Curves from https://www.thewindpower.net/ can be integrated in RESKit as shown in this [example](../../examples/1_load_input_data/1_3_1_process_power_curves_from_thewindpower_net.ipynb)
