In geomarker-io/addNarrData: Adds NARR Variables Based on Date and 12 x 12 km Grid Cell

Description

get averaged NARR data for lat, lon, start_date, and end_date

Usage

get_narr_data(
  d,
  type = "coords",
  narr_variables = c("hpbl", "vis", "uwnd.10m", "vwnd.10m", "air.2m", "rhum.2m",
    "prate", "pres.sfc"),
  ...
)

Arguments

d	data.frame with columns 'lat', 'lon', 'start_date', and 'end_date'
type	type of input data. either 'coords' if starting from lat and lon columns, or 'narr_cell' if starting from narr cell ids.
narr_variables	a character string of desired narr variables; a subset of c("hpbl", "vis", "uwnd.10m", "vwnd.10m", "air.2m", "rhum.2m", "prate", "pres.sfc")
...	further arguments passed onto s3::s3_get_files

Value

a data.frame identical to the input data.frame but with appended average NARR values

Examples

if (FALSE) {
d <- data.frame(
  id = c('1a', '2b', '3c'),
  lat = c(39.19674, 39.19674, 39.48765),
  lon = c(-84.582601, -84.582601, -84.610173),
  start_date = as.Date(c("3/8/17", "2/6/12", "6/18/20"), format = "%m/%d/%y"),
  end_date = as.Date(c("3/15/17", "2/13/12", "6/25/20"), format = "%m/%d/%y")
)

get_narr_data(d, narr_variables = c("air.2m", "rhum.2m"))
}
