The ESA Fire Disturbance Climate Change Initiative (CCI) project has produced maps of global burned area derived from satellite observations. The Harmonised Medium Resolution Burned Area grid product version 6.0 (MRBA60H) described here contains gridded data on global burned area derived from the harmonisation of two previous datasets: FireCCI51 and MRBA60 (previously known as FireCCIS311). This harmonisation has been done using machine learning techniques to try to approximate the FireCCI51 burned area to that of MRBA60 for the period when Sentinel-3 was not available (2003-2018). In that way, both datasets MRBA60H and MRBA60 can be used together in a consistent manner for time series analysis of burned area.

The description of the algorithm, input variables and validation results can be found in the Algorithm Theoretical Basis Document (ATBD) of the product in the linked documentation. The gridded dataset contains two variables: sum of burned area per month and per 0.25-degree grid cell, and the corresponding uncertainty, calculated as the Root Mean Square Error. For further information on the product and its format see the Product User Guide (PUG) in the linked documentation.
