| == Introduction ==
| |
| The EMD-WRF South Korea (ERA5) dataset is our most accurate, high-resolution mesoscale dataset covering South Korea and minor parts of Japan and North Korea. It is based on [[ERA5_Data|ERA-5]] reanalysis data from ECMWF (http://www.ecmwf.int) as its boundary conditions. As a premium dataset, a ‘EMD-WRF South Korea (ERA5)’ subscription gives you instant access to 45000+ continuously updated onshore and offshore mesoscale time series. The domain area is shown in the figure to the right.
| |
| | |
| Direct access to time series via windPRO’s user friendly Online Data Service - i.e. no delivery time!
| |
| | |
| The WRF mesoscale model is run in an optimized configuration at a high spatial resolution of 3km to produce hourly time series. Spatial visualization of the full domain is included via [http://www.windprospecting.com windprospecting.com] - and typically accessed from within windPRO.
| |
| | |
| At release time, the timespan of the data is at least 20 years back from today. Data access is via windPRO’s user friendly interface to on-line data and requires payment of an annual subscription fee. The EMD-WRF South Korea (ERA5) dataset is the successor of the [[EMD-WRF_South_Korea]].
| |
| | |
| == Release Schedule and Availability ==
| |
| Data is updated monthly with approximately 3 months delay defined by ERA-5's availability (from ECMWF), download time from the Copernicus Climate Datastore (from EU-Storage Servers) and computational efforts regarding EMD's high-performance computer clusters (from EMD). Before contacting support because of delays in the release schedule, please check ERA-5's availability on the ERA5 availability page (see link below). 'EMD-WRF South Korea (ERA5)' data cannot be computed at EMD HPC before ERA-5 data is available and have been downloaded to our storage system.

| | |
| == Dataset Parameters ==
| |
| A total of 127 sensors (parameters) are ready available for in-depth analysis directly in windPRO. The different parameters in the EMD-WRF South Korea (ERA5) dataset that are available from within windPRO are shown in the table below.
