The fire risk model uses satellite-derived products to estimate the flammability of ground litter based on modeled moisture content. Increased flammability in ground litter increases the likelihood that fires can burn and spread if ignition takes place. To estimate flammability and therefore fire risk, we can model the litter moisture daily using inputs of rainfall duration, land surface temperature (LST) and near-surface relative humidity (RH). LST and RH are derived from the daily, 5-km product MODIS atmospheric product MOD07L2 Atmospheric Profiles. Rainfall duration is calculated from the Global Precipitation Measurement (GPM) IMERG, 30-minute rainfall. The resulting fire risk map layer contains values from 1 to 40 with lower numbers corresponding to higher fire risk: purple to red colors represent very high to high risk (values of 1 to 10), orange to yellow represents moderate risk (value of 11 to 20), and green to blue colors represent low or very low risk (values 21 to 40). Further details about the model can be read in [Steininger et al. (2013)](http://link.springer.com/article/10.1007%2Fs00267-013-0073-1).
