%description
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)
<https://cfs.nrcan.gc.ca/publications?id=19973>) at various time scales:
the Fire Weather Index (FWI) System Wan Wagner (1985)
<https://cfs.nrcan.gc.ca/publications?id=19927> and the Fire Behaviour
Prediction (FBP) System Forestry Canada Fire Danger Group (1992)
<https://cfs.nrcan.gc.ca/pubwarehouse/pdfs/10068.pdf>. Some functions have
two versions, table and raster based.
