This dataset shows the predicted area of high fire potential for
the current year up to the end of the forecast period as simulated by a
modified version of the MC1 Dynamic General Vegetation Model (DGVM).
The area of high fire potential is
where PDSI and MC1-calculated values of potential fire behavior (fireline intensity
for forest and shrubland and rate of spread of spread for grassland) exceed
calibrated threshold values.
Potential fire behavior in MC1 is estimated using National
Fire Danger Rating System (NFDRS) formulas, monthly climatic (temperature,
precipitation, and relative humidity) data, and fuel moisture and loading estimates.
Monthly climatic data includes
recorded values up to the last observed month and forecast values provided by
the weather model identified in the dataset title.
Future climate forecasts have been made available through cooperation with the
International Research Institute for Climate Prediction (IRI) of Columbia University
which provides monthly updates of 7-month future climate forecasts from
