Parameters#

Parameter	Description	Default
`directory`	Directory containing ARL meteorology files for this met stream.	Required
`source`	arlmet source name for automatic downloading from NOAA archives (e.g. ‘hrrr’, ‘nam12’, ‘gdas1’, ‘gfs0p25’). When set, file_format and file_tres are not required. Source-specific constructor arguments (e.g. domain=’ak’ for nams) may be specified as additional inline fields.	`None`
`backend`	Download backend when source is set. One of ‘s3’, ‘ftp’, or ‘http’.	`'s3'`
`file_format`	Datetime format string used to discover meteorology filenames. Required when source is not set (archive mode).	`None`
`file_tres`	Nominal time spacing between meteorology files. Required when source is not set (archive mode).	`None`
`n_min`	Minimum number of meteorology files required for a run.	`1`
`subgrid_enable`	Enable meteorology subgridding before the run.	`False`
`subgrid_bounds`	Bounds used for meteorology subgridding.	`None`
`subgrid_buffer`	Buffer added around the receptor domain when subgridding meteorology.	`0.2`
`subgrid_levels`	Number of vertical levels to keep when subgridding meteorology.	`None`
`subgrid_dir`	Directory to cache subgridded met files. Defaults to <directory>/subgrid when not set. Shared across all simulations that use this met stream.	`None`
