Main File Surface/Flux (_FLX_)
This section describes the different data field stored in the main file for the surface and fluxes at the surface (…_FLX_…).
This file is only two-dimensional with a constant z=0.
The data stored in the .EDT files are in binary format and can be extracted using LEONARDO or XTract.
FIELD UNIT MEANING z_topo m Absolute Height of Model ground surface (always 0 in recent version) T Surface K Ground surface temperature T Surface Diff K Difference of ground surface to reference surface T Surface Change K/h Change of ground surface temperature q Surface g/kg Specific humidity of surface (availabe vapour) uv Above Surface m/s Wind speed at the first grid level above ground surface Sensible Heat Flux W/m² Sensible heat flux into the air (+: towards air) Exchange Coef. Heat m²/s Exchange coefficient for heat between sruface and air Latent Heat Flux W/m² Sensible heat flux into the air (+: towards air) Soil Heat Flux W/m² Heat flux into soil (+: directed towards deeper layers) SW Direct Radiation W/m² Direct shortwave radiation reaching ground surface SW Diffuse Radiation W/m² Diffuse shortwave radiation reaching ground surface Lambert Factor 0..1 Value of Lambert's law for solar angle Longwave Radiation Bud. W/m² Longwave radiation budget of ground surface Longwave Rad. from Vegetation W/m² Longwave radiation received from vegetation layers above (see remark 1) Longwave Rad. from Environment W/m² Longwave radiation received from buildings (see remark 1) Water Flux g/(m²s) Water flux from/to the ground surface Sky-View Factor 0..1 Sky View factor for z=0 (buildings only counted) Building Height m Height of building top (0 if no building assigned) Surface Albedo 0..1 Albedo of ground surface (see remark 2) Deposition Speed mm/s Deposition flux of analysed pollutant component Mass Deposed µg/m² Mass deposed at ground surface in µg
