`geophys_file`	a path to a geophysical data file generated using the 'calmet_define_geophys" function.
`resolution_scale_factor`	a factor by which the resolution of the receptors relates to the resolution of the CALMET domain.
`height_above_ground`	the chosen height above ground for all the discrete receptors.
`download_SRTM`	a choice of whether to download the SRTM GeoTIFF height data from a server or read the identical files from a local folder.
`SRTM_file_path`	path to a folder containing a collection of SRTM V4 zip archive files.
