| − | == Introduction ==
| |
| − | The initial [[ERA5 Data|ERA5 windPRO dataset]] released in 2017 is based on the raw ERA5 data on a reduced gaussian grid. Unfortuantely the newly released ERA5T (updated with a shorter delay) data is not available on the reduced gaussian grid, but only on the 0.25x0.25 grid available in the Climate Data Store. In order to have a dataset in windPRO with ERA5T data this ERA5 CDS Grid dataset is made available.

| − | == Data Parameters ==
| |
| − | EMD extracts a focused subset of climate-parameters from the ERA5 datasets - this subset focuses on wind-energy modelling. When the data have been processed at EMD, then the following parameters are available from within the online-data services within windPRO.
