In dKvale/aermod: Interface to EPA's air dispersion model AERMOD

Source options

Description

Create a data frame of AERMOD source options.

Usage

source_df(
  source_id = as.character(NA),
  description = as.character(NA),
  elevation_m = as.numeric(NA),
  x_coord = as.numeric(NA),
  y_coord = as.numeric(NA),
  type = c("point"),
  emit_gs = as.numeric(NA),
  height_m = as.numeric(NA),
  temp_k = as.numeric(NA),
  velocity_ms = as.numeric(NA),
  diameter_m = as.numeric(NA),
  downwash_file = as.character(NA),
  urban_pop = as.numeric(NA),
  group_id = as.character(NA)
)

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".

Examples

source_df(source_id     = c("SV01"),
          description   = c("boiler1"),
          elevation_m   = c(361.33),
          x_coord       = c(461874.9),
          y_coord       = c(4631367),
          type          = c("point"),
          emit_gs       = c(1),
          height_m      = c(10),
          temp_k        = c(600),
          velocity_ms   = c(30),
          diameter_m    = c(2),
          downwash_file = as.character(NA),
          urban_pop     = 60000,
          group_id      = as.character(NA))
