From: An estimate of carbon emissions from 2004 wildfires across Alaskan Yukon River Basin

  1. a The proportion (0.62) was assumed to be equivalent to areal portion of well-, and excessively well drained soil areas where whole litter/lichen/moss layer might be burned completely and no burning happened to poorly drained soils.
  2. b The average depth of organic (soil) is 15 cm. (The numbers in parentheses are the standard deviations of the means).
