trackdensity: Calculate density of trajectories

In metno/esd: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data

Calculate density of trajectories

Description

Internal function used in trajectory2density and events2field

Usage

trackdensity(
  lons,
  lats,
  track = NULL,
  dx = NULL,
  dy = NULL,
  radius = 5e+05,
  type = "track",
  verbose = FALSE
)

Arguments

lons	longitudes of trajectory
lats	latitudes of trajectory
track	trajectory number
dx	spatial resolution of output field in east-west direction (unit: degrees east)
dy	spatial resolution of output field in north-south direction (unit: degrees north)
radius	radius within which to look for trajectories for each grid point (unit: m)
type	"track" or "trajectory": calculate density of trajectories; "genesis", "cyclogenesis" or "start": calculate density of cyclogenesis events; "lysis", "cyclolysis" or "end": calculate density of cyclolysis events
verbose	if TRUE print progress
