the bounding box in WGS84 coordinates as a comma-separated character vector "xmin,ymin,xmax,ymax"


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.


An integer year to extract.


The name of a region. The available regions are:
na = North America
hi = Hawaii
pr = Puerto Rico


The frequency of the data. The available tempos are:
day = Daily data
mon = Monthly summary data
ann = Annual summary data
