Theoretical uncertainties for three global satellite-derived burned area estimates

Estimated annual burned area and uncertainties for three global satellite-derived burned area products. Each estimate is provided at 1° spatial resolution for the years 2001-2013. Theoretical annual uncertainties in burned area (standard errors) products are generated according to a multiplicative triple collocation error model and annualised according to a sampling of the 16-day burned area estimates from each product. The approach provides unique uncertainties at 1° for the NASA Moderate Resolution Imaging Spectroradiometer (MODIS) Collection 6 burned area product (MCD64); the MODIS Collection 5.1 MCD45 product and the FireCCI50 product. Please note that due to limitations in the available sampling for the error model, around 40% of cells do not have uncertainty estimates.

三款全球卫星反演火烧面积产品的年度火烧面积估算值及其不确定性。所有估算值均采用1°空间分辨率，覆盖2001至2013年时段。火烧面积产品的年度理论不确定性（标准误差）基于乘性三重搭配误差模型生成，并通过对各产品的16天尺度火烧面积估算值进行采样实现年度化处理。本方法可为美国国家航空航天局（National Aeronautics and Space Administration, NASA）中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）第6版火烧面积产品（MCD64）、MODIS第5.1版MCD45产品以及FireCCI50产品提供1°分辨率下的专属不确定性估算结果。请注意，由于误差模型可用采样存在局限性，约40%的网格单元未提供不确定性估算值。
