ERA5CDS Data
Introduction
The initial 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.
| Parameter | Unit | Description |
|---|---|---|
| time | UTC time stamp | |
| wSpeed.10 | m/s | Wind speed @ 10m |
| wDir.10 | deg | Wind direction @ 10m |
| wSpeed.100 | m/s | Wind speed @ 100m |
| wDir.100 | deg | Wind direction @ 100m |
| temperature.2 | deg.celcius | Temperature @ 2m |
| dewPointTemp.2 | deg.celcius | Dew point temperature @ 2m |
| rh.2 | % | Relative humidity @ 2m |
| psfc | pa | Surface pressure |
| msl | pa | Mean sea-level pressure |
| blh | m | Boundary layer height |
| tcc | % | Total cloud cover |
| heatFlux | w/m2 | Instantaneous surface sensible heat flux |
| zust | m/s | Friction velocity |
| cbh | m | Cloud base height |
| ssrdAcc | w/m2 | Surface solar radiation downwards |
| era5t | 0/1 | Binary variable indicating whether the sample is ERA5T data |
