Fire Danger Assessment Using Moderate-Spatial Resolution Satellite Data

Fire is one of the most common disturbances in natural ecosystems. The analysis various sources information (official and unofficial) about fires Ukraine (2019–2020) showed a lack timely reliable information. Satellite observation crucial importance to provide accurate, reliable, This paper aims modify index fire danger forest’s FWI by increasing its precision, based on use higher spatial resolution satellite data. A modification method involves utilization soil moisture deficit, addition six subindices system. In order calculate values, weather data from Copernicus Atmosphere Monitoring Service were used. Soil deficit calculated using Sentinel-1 radar water saturation degree surface layer geospatial parameters 3D Hydraulic Database Europe. application proposed methodology specified satellite, weather, makes it possible assess continental scale with 250 m, 1 km, daily temporal resolution. Validation for modifying system demonstrates an improvement precision relevance prediction.
