Estimates glacier surface area and glacier volume.
Source:R/glacierAreaVolume_Aizen.R
glacierAreaVolume_Aizen.Rdlength, surface area and volume found by Aizen et al. in the Tien Shan mountains. They can be used to estimate regional glacier volumes.
Arguments
- glaciers
A data.frame, tibble, or sf object. Must contain an attribute ```Lmax``` in meters (as in the Randolph Glacier Inventory (RGI 6.0)) or ```Length [km]``` in kilometers or ```L(t) [km]``` (as in the output from Oerlemans glacier length function).
Value
Returns the input object with Area_Aizen_km2 and Volume_Aizen_km3 added. Will return NULL if the length column in the input object is not found.
