A schematic of the FireBGCv2 model. The right diagram shows important ecological processes and the scale that they are simulated including the mountain pine beetle (MPB), fire, climate, and fuel treatments (Land use). The middle diagram shows the five scales represented in FireBGCv2. Stand-level processes are simulated on a vignette of a stand called a plot. This plot is comprised of various ecosystem components (upper right panel). The flow of energy, carbon, water, and nitrogen is simulated across each of these components using mechanistic algorithms detailed in the Keane et al. (2011) document. Biophysical processes such as evaporation, transpiration, photosynthesis, and respiration are governed by five daily weather variables: precipitation, maximum and minimum temperature, radiation, and humidity
