lon_lat_fine {rainfarmr}

Linear interpolation of longitude and latitude vectors to higher resolution

Description

Longitude and latitude vectors are interpolated higher resolution increasing dimensions by a factor nf. The grid spacings of the first two and of the last two elements are used to extrapolate at the boundaries.

Usage

lon_lat_fine(lon, lat, nf)

Arguments

lon

vector of longitudes.

lat

vector of latitudes.

nf

factor by which to increase resolution.

Value

List with elements lon and lat with resolution increased by factor nf.
