Arguments

source_id

Emission source ID or name.

description

Short description of emission source as a text string.

elevation_m

Source elevation in meters.

x_coord

X coordinates of source.

y_coord

Y coordinates of source.

type

Type of source to be modeled in AERMOD. Options: (1) "point", (2) "volume", or (3) "area".

emit_gs

Emission rate for source in grams/second.

height_m

Height of source in meters.

temp_k

Exit temperature of air emissions in degrees Kelvin.

velocity_ms

Exit velocity of air emissions in in m/s.

diameter_m

Internal diameter of stack in meters.

downwash_file

Path to downwash parameters for each emission source.

urban_pop

Urban population for source. Requires a value of at least 100. If blank or a value less than 100, source is modeled with default rural dispersion coefficients.

group_id

Group IDs assigned to source. To assign a source to multiple groups use a vector: c("ALL", "SV01", "SV01_to_SV03". If blank, source is assigned to group "All".
