Tiles are specified by a tile ID, year, and element;
Tiles are downloaded in the NetCDF format. download_daymet_tile returns the path to the downloaded NetCDF tile files.
download_daymet_tile(tileID, elements, years, raw.dir)A numeric indicating the DAYMET tile ID number.
A character vector of elements to extract. The available elements are: dayl = Duration of the daylight period in seconds per day. This calculation is based on the period of the day during which the sun is above a hypothetical flat horizon. prcp = Daily total precipitation in millimeters per day, sum of all forms converted to water-equivalent. Precipitation occurrence on any given day may be ascertained. srad = Incident shortwave radiation flux density in watts per square meter, taken as an average over the daylight period of the day. NOTE: Daily total radiation (MJ/m2/day) can be calculated as follows: ((srad (W/m2) * dayl (s/day)) / l,000,000) swe = Snow water equivalent in kilograms per square meter. The amount of water contained within the snowpack. tmax = Daily maximum 2-meter air temperature in degrees Celsius. tmin = Daily minimum 2-meter air temperature in degrees Celsius. vp = Water vapor pressure in pascals. Daily average partial pressure of water vapor.
A numeric vector of years to extract.
A character string indicating where raw downloaded files should be put. The directory will be created if missing. Defaults to './RAW/DAYMET/'.
A named list of character vectors, each representing the full local paths of the tile downloads.
