The dataset for relative humidity is based on the in-situ data (2018) and the guidance on how to use ensemble datasets. The spread is calculated as the difference between the 5th and 95th percentiles over the ensemble to provide a measure indicate of the 90% uncertainty range. The mean across the members is calculated and is provided as the 'best-guess' fields. For each of the members of the ensemble a spatially correlated random field is produced using a pre-calculated spatial correlation function. The ensemble dataset is constructed through a conditional simulation procedure. The Global 30 Arc-Second Elevation Data Set ( GTOPO30), a global raster Digital Elevation Model (DEM) with a horizontal grid spacing of 30 arc seconds (approximatelyġ kilometer) developed by USGS is used for the elevation file as well. Sum RR, daily mean sea level pressure PP, daily mean wind speed FG, daily mean relative humidity HU and global radiation QQ.
