The domain contains various street configurations, open spaces, water surfaces, orography and building heights. The simulations were performed with different initial wind speeds, rain amounts, wind directions, and domain configurations. The simulations cover 1:40 hours, starting at 7:30 LST (LST refers to Local Solar Time), with a temporal resolution of 10, 1 or 5 minutes. This experiment contains a selection of output variables, control variables are not included. The file names of the data sets are composed as follows. {precipitation}_{intensity}_{windspeed}_ {intensity}_{winddirection}_{value}_{case ID}.nc There are 3 intensities: low, medium, high Associated values are these: pr_low = 0.5 mm, pr_medium =0.9 mm, pr_high = 1.7 mm (after 10 minutes) ff_low = 2 m/s, ff_medium = 4 m/s, ff_high = 4 m/s Example: pr_medium_ff_low_dd_270_ML27.nc Dr. David Grawe University of Hamburg http://www.mi.uni-hamburg.de/ pointOfContact NetCDF ATMODAT EASYDAB FOS: Earth and related environmental science Hamburg-Mitte Precipitation atmos atmosphere atmospheric model atmospheric precipitation obstacle-resolving model urban urban canopy effects wind field CC-BY-4.0: Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ eng; USA 9.9787 10.0072 53.5428 53.558 Local Solar Time in arbitrary year 2000-01-21 2000-01-21 height_above_mean_sea_level "Height_above_X" means the vertical distance above the named surface X. "Mean sea level" means the time mean of sea surface elevation at a given location over an arbitrary period sufficient to eliminate the tidal signals. [CF-Standard Name]; unit: not filled air_temperature Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: not filled air_density [CF-Standard Name]; unit: not filled projection_x_coordinate "x" indicates a vector component along the grid x-axis, when this is not true longitude, positive with increasing x. Projection coordinates are distances in the x- and y-directions on a plane onto which the surface of the Earth has been projected according to a map projection. The relationship between the projection coordinates and latitude and longitude is described by the grid_mapping. [CF-Standard Name]; unit: not filled relative_humidity relative_humidity [CF-Standard Name]; unit: not filled projection_y_coordinate "y" indicates a vector component along the grid y-axis, when this is not true latitude, positive with increasing y.

The relationship between the projection coordinates and latitude and longitude is described by the grid_mapping. [CF-Standard Name]; unit: not filled x_wind "x" indicates a vector component along the grid x-axis, when this is not true longitude, positive with increasing x. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)[CF-Standard Name]; unit: not filled upward_air_velocity vertical wind velocity A velocity is a vector quantity. "Upward" indicates a vector component which is positive when directed upward (negative downward). Upward air velocity is the vertical component of the 3D air velocity vector. [CF-Standard Name]; unit: not filled air_pressure air_pressure [CF-Standard Name]; unit: not filled surface_altitude The surface called "surface" means the lower boundary of the atmosphere. Altitude is the (geometric) height above the geoid, which is the reference geopotential surface. The geoid is similar to mean sea level.[CF-Standard Name]; unit: not filled y_wind "y" indicates a vector component along the grid y-axis, when this is not true latitude, positive with increasing y.
