Fire Parameterization in CLM

The article discusses the fire parameterization in the Community Land Model (CLM), which is composed of four main components:

1. Non-peat fires outside cropland and tropical closed forests
2. Agricultural fires in cropland
3. Deforestation fires in tropical closed forests
4. Peat fires

The fire parameterization takes into account various factors that influence burned area, including climate and weather conditions, vegetation composition and structure, and human activities. After calculating the burned area, the model estimates the fire impact, which includes:

- Biomass and peat burning
- Fire-induced vegetation mortality
- Adjustment of the carbon and nitrogen (C/N) pools
- Fire emissions

The article cites several references (Li et al. 2012a, 2012b, 2013; Li and Lawrence 2017) for more details on the fire parameterization in the CLM.
