Estimates glacier surface area and glacier volume.

ErazovsGlacierFunction implements the empirical relationship between glacier area and volume. It can be used to estimate regional glacier volumes in Central Asia.

Usage

ErazovsGlacierFunction(glaciers)

Arguments

glaciers

A data.frame, tibble, or sf object. Must contain an attribute "Area" in kilometers squared (as in the Randolph Glacier Inventory (RGI 6.0)).

Value

Returns the input object with Volume_Erazov_km3 added. Will return NULL if the length column in the input object is not found.

Note

This function is being deprecated. Please use glacierVolume_Erasov() instead.
