Description
The data set contains the fire perimeters for Ukraine for 2023 sourced from remote sensing data. The locations and dates of burning were detected using MODIS/VIIRS products on thermal anomalies. This information was used to select pre- and post-fire Copernicus Sentinel 2 L2A imagery. Satellite images were screened from clouds, cloud shadows and combined into median composite mosaics. The image mosaics were created using all available imagery within a 14-day time window before (pre-fire mosaic) and after (post-fire mosaic) each fire. Fire perimeters were visually delineated by comparing post and pre-fire image mosaics using a SWIR2–NIR–Red band combination. The spatial accuracy of fire perimeters corresponds to Sentinel 2 data at 20-m spatial resolution.
Delineated fire perimeters were intersected with the Copernicus Dynamic Land Cover map at 100 m resolution (v.3.0.1) to extract burned areas of five land cover classes according to the following reclassification scheme of the original pixel values.

MetaData
|
Field name |
Description |
| id | Unique identifier of each fire perimeter |
| longitude | Longitude referring to centroids of fire perimeters |
| latitude | Latitude referring to centroids of fire perimeters |
| date | Date of burning in the format DD.MM.YYYY |
| year | Year |
| month | Month |
| day | Day of the month |
| week | Week number in the year |
| reg | The capital city name of the Ukrainian regions (oblast) associated with each fire |
| occupied | A binary indicator variable referring to the locations of each fire within the Russian-occupied territory (1) or within the territory controlled by the Government of Ukraine (0) for a given date |
| buff_30km | A binary indicator variable referring to the location of each fire within a 30-km buffer zone on both sides of the front line. In contrast to a daily progression front line used to detect "occupied" territory, the buffer was calculated using the farthest position of a frontline towards territories controlled by the Government of Ukraine |
| emerald | A binary indicator variable referring to locations of each fire within the Emerald network |
Burned areas by land cover (LC) type (in hectares) within the fire perimeter according to the Copernicus Dynamic Land Cover map at 100 m resolution (v.3.0.1)
| LC_0 | N/A |
| LC_1 | Coniferous forest |
| LC_2 | Broadleaved forest |
| LC_3 | Other natural landscape |
| LC_4 | Agricultural land |
| LC_5 | Settlement |
