return trajectory

Usage

obs_traj_foot(
  ident,
  part = NULL,
  timelabel = NULL,
  pathname = "",
  foottimes = 0:240,
  zlim = c(0, 0),
  coarse = 1,
  dmassTF = TRUE,
  numpix.x = 70,
  numpix.y = 70,
  lon.ll = -145,
  lat.ll = 11,
  lon.res = 1,
  lat.res = 1,
  npar = 500,
  eps.global = 0.1
)

Arguments

part

data.table with PARTICLE.DAT information

foottimes

vector of times between which footprint or influence will be integrated

zlim

(if not default 0,0): vertical interval for which particle distribution is looked at

dmassTF

default TRUE weighting by accumulated mass due to violation of mass conservation in met fields

numpix.x

number of pixels in x directions in grid

numpix.y

number of pixels in y directions in grid

lon.ll

lower left corner of grid (longitude of southwest corner of southwest corner gridcell)

lat.ll

lower left corner of grid (latitude of southwest corner of southwest corner gridcell)

npar

default 500, number of particles hysplit was run with (required in order to account for those cases where a thinned particle table that may not contain all particle indices is used)

Value

return footprint
