Wind related: WD - Wind direction (degrees); WS - Wind speed (m s − 1 ), TKE - Turbulent kinetic energy (m 2 s 2 );
Temperature related: Tpot - Potential temperature (K); Ta - Air temperature (T s ) - Temperature of the surface w walls, g ground and r roof, R road, s soil, V
vegetation; U urban slab, Init - initial condition;
Humidity: T w - Wet Bulb T (C); e a - Water vapour pressure (hPa); RH - Relative humidity (%); SH - Specific humidity (units U1: g kg − 1 , U2: kg kg − 1 U3:

Radiation: K ↓ - incoming shortwave radiation; S - direct radiation; D - diffuse radiation; L ↓ - incoming longwave radiation; CC - cloud cover; Z - Solar
zenith angle; C p - specific heat; P - Atmospheric pressure (hPa); ρ - Air Density (kg m 3 ); R - Precipitation (kg m 2 s − 1 );
Soil: Tprofile - temperature profile; θ - Soil moisture content; T water - Water temperature (K/C);
Q F - Anthropogenic heat flux (W m − 2 ).
