get_awc: Extract the AWP for a Coordinate Pair

In cszang/awc: Get Soil Water Holding Capacity from Webb et al.'s Data Base

Description

Extract AWC for Point from Webb et al.'s data base

Usage

get_awc(coords)

Arguments

coords

a list with lon and lat giving the coordinates

Details

This function extracts the AWC for a given point (list of coordinates as lon and lat). In case there no value at point, the functions looks around a bit to find the next gridpoint that is not NA.

The data set used is the texture derived soil water holding capacity from Webb et al., that is freely available via http://daac.ornl.gov/SOILS/guides/Webb.html

Value

a single value for AWC (in mm)
