C2.1 Atmospheric Receptor File: Data
see also: General File Structure, Surface Receptor Data, Soil Receptor Data
This section describes the different data field found in the atmospheric receptor files. Both receptor files, snapshot and time series file , hold the same data fields (see Overview).
Data contained in the atmospheric receptor files:
FIELD UNIT MEANING

Time - Model time of clock at output (String)
modTime (min) Model time in min since start
z m Model height of data
u m/s Wind speed u-component
v m/s Wind speed v-component
w m/s Wind speed w-component
wSpeed m/s Total wind speed
wDir ° Wind direction, 0=North, Rotation corrected
