C2.2 Surface/ Flux Receptor File: Data
see also: General File Structure, Soil Receptor Data, Atmospheric Receptor Data
This section describes the different data field found in the surface/flux receptor files. Only time series files will be produced for the surface data (see Overview).
Data contained in the surface receptor files:
NR FIELD UNIT MEANING
1 Date - Date of the model time (String)
2 Time - Model time of clock at output (String)
3 modTime min Model time in min since start
4 z m Always zero, for compatibility with the other receptor files
5 T0 K Surface Temperature
6 dT0/dt K/h Change in Surface Temperature (see remark)
7 q0 g/kg Surface Humidity
8 uv1 m/s Horizontal Wind Speed above surface
9 w1 m/s Vertical Component Wind Speed above surface (positive: upward)
9 T1 K Air temperature of grid point above the surface
10 H W/mē Sensible Heat Flux
11 LE W/mē Latent Heat Flux
12 G W/mē Soil Heat Flux, positive: directed into the soil
13 Km mē/s Mass Exchange Coefficient at Surface
14 Kh m2/s Turbulent Exchange Coefficient for Heat at Surface
15 Qkw.dir W/mē Max Direct Shortwave Radiation (see remark)
16 Qkw.dif W/mē Max Diffuse Shortwave Radiation
17 Qlw.Budg W/mē Longwave Radiation Budget of surface
18 Qlw.surf W/mē Longwave Emission of Surface
19 Qlw.sky W/mē Absorbed Longwave Radiation from the Sky (see remark)
20 Qlw.leafs W/mē Absorbed Longwave Radiation from Vegetation (see remark)
21 Qlw.envir W/mē Absorbed Longwave Radiation from Environment (Buildings)(see remark)
