Randomized trial validates burned area products in southern Africa, indicating accuracy variations between them.

The study aims to validate three global burned area products using independent reference data.
Validation conducted using data from 11 Landsat scenes across southern Africa.
Accuracy evaluated via confusion matrices for local applications and regression metrics for broader applications.
Consideration of a burning season to compare different burned area products.
Quantitative results reveal notable differences in accuracy among the MODIS, L3JRC, and GlobCarbon products.
Confusion matrix metrics showed varying levels of accuracy for local applications.
Linear regression analysis indicated differences in product performance on coarser scales.

Roy et al. (2009) studied this question.
