calculate_ice_thickness: Calculate ice thickness

In WDNR-Water-Use/CSLSchem: CSLS Water Chemistry Analysis

Description

Calculates the thickness of ice on a lake. Assumes a linear increase from a static ice-on date to a static ice-off date with a static date of max thickness and a static max thickness.

Usage

calculate_ice_thickness(
  date,
  ice_on = 320,
  ice_off = 105,
  ice_max = 60,
  ice_max_depth = NISTunits::NISTinchTOmeter(24) * 1000
)

Arguments

date	date to calculate ice thickness (POSIX)
ice_on	day of year when ice starts forming. Defaults to day 320 (Nov 16).
ice_off	day of year when ice is all gone. Defaults to day 105 (Apr 15)
ice_max	day of year when ice thickness is at a maxiumum. Defaults to day 60 (Mar 1).
ice_max_depth	max thickness of ice (m). Defaults to 24 inches.

Value

ice_depth, a numeric value of ice thickness (m).
