Grassland Fire Danger Index
Grassland Fire Danger Index (GFDI) was originally used in Australia1 and then adapted for the United States. The National Weather Service (NWS) in Wichita began utilizing the GFDI in their county warning area in 20102. However, the data is only available for those particular counties in the central portion of the state. This map utilizes the same equation used by the NWS and applies it to the entire state. Curing data used to generate the map is determined by averaged greenness over the county. This satellite data is obtained over a week period, updated once a week, and distributed through the Earth Resources and Observation and Science (EROS) Center3. Forecast data is pulled from the NWS National Digital Forecast Database4 (NDFD) at the centroid of each county.
This product is meant to provide overall guidance on fire danger. It is NOT intended to be a decision-making tool - please contact your local NWS office for specific forecasts.
