This is a python translation of the R code available from cran - this does not include all the functionality available in that package yet.
This project provides a group of new functions to calculate the outputs of the two main components of the Canadian Forest Fire Danger Rating System (CFFDRS) Van Wagner and Pickett (1985) at various time scales: the Fire Weather Index (FWI) System Wan Wagner (1985) and the Fire Behaviour Prediction (FBP) System Forestry Canada Fire Danger Group (1992). Some functions have two versions, table and raster based.
