Fire burned area from 2001 to present derived from satellite observations

The Burned Area products provide global information of total burned area (BA) at pixel and grid scale. The BA is identified with the date of first detection of the burned signal in the case of the pixel product, and with the total BA per grid cell in the case of the grid product. The products were obtained through the analysis of reflectance changes from medium resolution sensors (Terra MODIS, Sentinel-3 OLCI), supported by the use of MODIS thermal information. The burned area products also include information related to the land cover that has been burned, which has been extracted from the Copernicus Climate Change Service (C3S) land cover dataset, thus assuring consistency between the datasets.
The algorithms for BA retrieval were developed by the University of Alcala (Spain), and processed by Brockmann Consult GmbH (Germany).
Different product versions are available. FireCCI v5.0cds and FireCCI v5.1cds were developed as part of the Fire ECV Climate Change Initiative Project (Fire CCI) and brokered to C3S, offering the first global burned area time series at 250m spatial resolution. FireCCI v5.1cds used a more mature algorithm than the previous version. This algorithm was adapted to Sentinel-3 OLCI data to create the C3S v1.0 burned area product, extending the BA database to the present.
During July 2020, an error in some files in the version v5.1cds were identified, affecting the files of the grid product of January 2018, and the pixel and grid products of October, November and December 2019. These errors were fixed, and a new version, v5.1.1cds, was created for the whole time series, to replace version v5.1cds. The latter product has been deprecated, but it is temporally kept in the database for transparency and traceability reasons. Only version v5.1.1cds should be used.
The BA products are useful for researchers studying climate change, as they provide crucial information on burned biomass, which can be translated to greenhouse gases emissions amongst other contaminants. Burned area is also useful for land cover change studies, fire management and risk analysis.

燃烧区域产品提供了全球范围内的总燃烧区域（BA）在像素和网格尺度上的信息。对于像素产品，BA通过首次检测到燃烧信号的日期进行识别；而对于网格产品，则是以每个网格单元的总BA进行识别。这些产品是通过分析中分辨率传感器（如Terra MODIS、Sentinel-3 OLCI）的反射率变化而获得的，并得到了MODIS热信息的支持。燃烧区域产品还包括有关已燃烧土地覆盖的信息，这些信息是从哥白尼气候变化服务（C3S）的土地覆盖数据集中提取的，从而确保了数据集之间的数据一致性。BA检索算法由西班牙阿尔卡拉大学（University of Alcala）开发，并由德国的Brockmann Consult GmbH（Brockmann Consult GmbH）进行处理。不同的产品版本可供选择。FireCCI v5.0cds和FireCCI v5.1cds作为Fire ECV气候变化倡议项目（Fire CCI）的一部分被开发，并经C3S代理，提供了全球首个250米空间分辨率的燃烧区域时间序列。FireCCI v5.1cds采用了比前一版本更为成熟的算法，该算法被适配至Sentinel-3 OLCI数据，以创建C3S v1.0燃烧区域产品，将BA数据库扩展至当前。在2020年7月，发现了v5.1cds版本中某些文件的错误，影响了2018年1月的网格产品以及2019年10月、11月和12月的像素和网格产品。这些错误已得到修复，并创建了新的版本v5.1.1cds，以替换整个时间序列的v5.1cds版本。后者产品已被弃用，但出于透明度和可追溯性的原因，暂时保留在数据库中。应仅使用v5.1.1cds版本。BA产品对研究气候变化的研究人员来说非常有用，因为它提供了关于燃烧生物量的关键信息，这些信息可以转化为温室气体排放以及其他污染物。燃烧区域对于土地覆盖变化研究、火灾管理和风险评估也具有重要意义。
