soil

Soil properties (such as soil moisture, emissivity and the reflectance spectrum)

Initialized

SCOPE.m

soil.Tsold may be changed by ebal() if options.soil_heat_method < 2 (default case)

soil.rss, soil.rbs may be calculated by calc_rssrbs() if options.calc_rss_rbs is selected

soil.GAM produced by Soil_Inertia0() or Soil_Inertia1() if options.soil_heat_method
