                         conditions, population density, agriculture, and lightning. 
                         Recently, fire frequency and severity have induced health problems 
                         and contributed to increase atmospheric greenhouse gases. Based on 
                         atmospheric susceptibility to fire, this study evaluates the use 
                         of a Potential Fire Index (PFIv2) to identify regions prone to 
                         fire development, as demonstrated by the satellite detected-fire 
                         in the 2001-2016 interval. It is demonstrated that PFIv2 delivers 
                         an efficiency by up to 80% in matching the observed fires from 
                         Terra/MODIS satellite. The PFIv2 is also able to reproduce more 
                         accurately areas with fire activity with respect to its previous 
                         version, the PFI. This better performance is linked to the 
                         implementation of parameterization of water pressure deficit and 
                         atmospheric stability in the lower troposphere, and a new term to 
                         represent the effect of surface temperatures, particularly in 
                         mid-latitudes and extra-Tropics. To evaluate the performance of 
                         the PFIv2 in more details, its comparison to MODIS burned areas 
                         demonstrated correlations values higher than 0.6 over the most 
                         susceptible regions such as Africa and South America, slightly 
                         lower correlation is found where fire does not primary follows the 
                         climate annual cycle, and is dominated by high frequency events. 
                         These findings indicate that the PFIv2 can be an important tool 
                         for decision makers in predicting the potential for vegetation 
                         fires development and fire danger.",
