Large-eddy simulation during the Wind and Storms Experiment (WASTEX)

The ICOsahedral Nonhydrostatic (ICON) model was run with one-way nesting on four nested domains with 623, 311, 156 and 78 m grid spacing and 150 vertical levels over the Upper Rhine Valley. Only wind from 78 m data is available here.

The data are saved in hourly files, e.g. at 06 UTC: LL_078m_wind_3D_10m_DOM04_ML_20170223T060000Z_zoom Files are in netCDF format with the following structure: netcdf LL_078m_wind_3D_10m_DOM04_ML_20170223T060000Z_zoom { dimensions: time = UNLIMITED ; // (6 currently) lon = 450 ; lat = 450 ; height = 40 ; bnds = 2 ; height_2 = 40 ; variables: double time(time) ; time:standard_name = "time" ; time:units = "day as %Y%m%d.%f" ; time:calendar = "proleptic_gregorian" ; time:axis = "T" ; double lon(lon) ; lon:standard_name = "longitude" ; lon:long_name = "longitude" ; lon:units = "degrees_east" ; lon:axis = "X" ; double lat(lat) ; lat:standard_name = "latitude" ; lat:long_name = "latitude" ; lat:units = "degrees_north" ; lat:axis = "Y" ; double height(height) ; height:standard_name = "height" ; height:long_name = "generalized_height" ; height:axis = "Z" ; height:bounds = "height_bnds" ; double height_bnds(height, bnds) ; double height_2(height_2) ; height_2:standard_name = "height" ; height_2:long_name = "generalized_height" ; height_2:axis = "Z" ; float ua(time, height, lat, lon) ; ua:standard_name = "eastward_wind" ; ua:long_name = "Zonal wind" ; ua:units = "m s-1" ; ua:param = "2.2.0" ; float va(time, height, lat, lon) ; va:standard_name = "northward_wind" ; va:long_name = "Meridional wind" ; va:units = "m s-1" ; va:param = "3.2.0" ; float wa(time, height_2, lat, lon) ; wa:standard_name = "upward_air_velocity" ; wa:long_name = "Vertical velocity" ; wa:units = "m s-1" ; wa:param = "9.2.0" ; Three-dimensional wind components are stored in variables "ua", "va" and "wa" as function of coordinates "time", "height/height_2", "lat" and "lon".
