In ropensci/FedData: Functions to Automate Downloading Geospatial Data Available from Several Federated Data Sources

Download the 1-km DAYMET daily weather dataset for a region as a netcdf.

Description

Data are downloaded in the NetCDF format. download_daymet_thredds returns the path to the downloaded NetCDF file.

Usage

download_daymet_thredds(bbox, element, year, region, tempo)

Arguments

bbox	the bounding box in WGS84 coordinates as a comma-separated character vector "xmin,ymin,xmax,ymax"
element	An element 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.
year	An integer year to extract.
region	The name of a region. The available regions are: na = North America hi = Hawaii pr = Puerto Rico
tempo	The frequency of the data. The available tempos are: day = Daily data mon = Monthly summary data ann = Annual summary data

Value

A named list of character vectors, each representing the full local paths of the tile downloads.
