Forest Fire Risk Indices
Forest Fire Index | Fosberg Fire Weather Index | Drought IndexForest Fire Index
The Forest Fire Index estimates the risk of forest fires based on moisture information of three different soil layers. The index ranges from 0 to 1, where the risk increases for values exceeding 0.5. A value of 0 indicates low risk, while a value of 1 indicates very high risk.forest_fire_warning:idx

Drought Index
This index forecasts whether a certain location is under a drought or not. The percentiles of the deviation of the current time window from the mean of the past years is computed. The percentiles are then grouped into bins which gives the following output scale for the drought index:Percentile | 0-10 | 10-20 | 20-30 | 30-40 | 40-60 | 60-70 | 70-80 | 80-90 | 90-100 |
