GFAS wildfire fraction of area observed (offire, dimensionless, paramter ID: 97.210)

Hello everyone,

I'm using GFAS inventory to study the emission of a wildfire. However, I found the wildfire fraction of area observed, offire, is larger than 1. Sometimes for the non-wildfire areas, the values are still larger than 1. 

For instance, a small fire (36 ha) occurred on 14 September 2020 at 47.3726°N, 2.12987° E. As shown below, the offire values are larger than 1 at this location. In fact, locations around this place also have offire values larger than 1. 

So, I could not use this parameter to calculate the burned area (grid area*offire). Does anyone know how to use offire? And how to calculate the burned area with GFAS?

Thank you!


I have the same problem and don't know how to solve it. I need to calculate the fires areas and the 'offire' table should be a fraction (0:1) but has often values between 0 and 6.

Does anyone knows how to use this parameter or correct it?
