hrs_rand: Generate random hours of operation

In jlovegren0/aermod: Work with AERMOD POST files

Description

Generate random hours of operation over the meteorological database. Hours within each meteorological year are randomly sampled (without replacement). Random sampling can consider blocks of consecutive hours, or individual hours (block length of 1).

Usage

hrs_rand(
  yrspan = 2016L:2020L,
  nblock = 6L,
  blocklen = 1L,
  which_filter = 1L,
  units = c("hours", "days"),
  emis_scale = 1
)

Arguments

yrspan	Calendar years for which operating hours are to be generated. A numeric vector
nblock	Number of blocks of consecutive hours.
blocklen	Number of hours in each block. Default is 1.
which_filter	Integer specifying special filters on the random number generation. Default is 1 (no filter). 2 is case where nblock = 1 and blocks in successive years must be spaced at least 365 days apart.
units	for blocklen, either "hours" (default) or "days". Return value is always vector of hours.
emis_scale	, for binned randomized emission rates, a vector of emission scalars of length blocklen. Default is 1 (no binning).

Value

An integer vector of operating hours, which may be used to index rows in an impact matrix.
