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
