The BIO_BURN_5X5_HAO_NAT data set contains data representing the geographical and temporal distribution of total amount of biomass burned. The data were collected by Dr. Wei Min Hao and Mei-Huey Liu from ground stations located in Africa, Asia, and tropical America (Central and South America). Data are available for 1980. Each measurement consists of four parameters: amount of biomass burned in forest fires, amount of biomass burned in savanna fires, amount of fuel wood and agricultural residues burned, and total amount of biomass burned. Each granule consists of one year of data per region.
