DAYMET point values

Description

Downloads DAYMET climate variables for specified point and time-period

Usage

daymet.point(
  lat,
  long,
  start.year,
  end.year,
  site = NULL,
  files = FALSE,
  echo = FALSE
)

Arguments

lat	latitude of point (decimal degrees WGS84)
long	longitude pf point (decimal degrees WGS84)
start.year	First year of data
end.year	Last year of data
site	Unique identification value that is appended to data
files	(TRUE/FALSE) Write file to disk
echo	(TRUE/FALSE) Echo progress

Details

data is available for Long -131.0 W and -53.0 W; lat 52.0 N and 14.5 N Function uses the Single Pixel Extraction tool and returns year, yday, dayl(s), prcp (mm/day), srad (W/m^2), swe (kg/m^2), tmax (deg c), tmin (deg c), vp (Pa) Metadata for DAYMET single pixel extraction: https://daymet.ornl.gov/files/UserGuides/current/readme_singlepointextraction.pdf

Value

A data.frame with geographic coordinate point-level climate results
