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.

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 Surface 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
