Create a wind_field

Creates a wind_field, the wind across a grid at a single moment, from a two-layer raster or file, or from one time step of a wind_series. To summarize a whole series as a single field, use mean() or net_flow().

Usage

wind_field(x, step = NULL)

Arguments

x

A SpatRaster with two layers holding the u and v wind components, the path to a raster file with those two layers, or a wind_series. Data must be on a longitude/latitude grid, with components in m/s, oriented to true east and north.

step

For a wind_series with more than one time step, the time step to use, as an integer index (see wind_times() for the time of each step).

Value

A wind_field object, which is a particular form of SpatRaster.

See also

mean() for the time-mean wind of a series.

Examples

series <- windscape_example("wind_series")
field <- wind_field(series, step = 1)
