Receptor Data
Contains the state of the receptors data in your model area, divided into atmospheric, surface/flux, and soil data.
The receptor data files are produced each receptor output interval (default: 10 min) and represent the general state of the receptor at the given model time. The atmosphere and soil data are saved as a file for each individual output that contains the information for every cell height (1DR file). Additionally, the data over the whole simulation time is saved in one file (1DT). The flux data is only saved in a 1DT file.
Variable list
This list represents the general variable structure. The actual sequence of the variables might differ but the same information is stored in total.
