This is because a rise in emissions from deforestation for cropland largely counteracted the decline in wildfire emissions over the past century. (carbonbrief.org)
Though ground and aircraft sensors provide the most accurate measurements of carbon monoxide for a localized area, satellites offer the best way to monitor wildfire emissions over broad regions, particularly in remote areas where there are fewer ground - based instruments.

The two largest factors influencing wildfire emissions included land use change, such as the conversion of forests to cropland, and local population increases, the researchers say. (carbonbrief.org)
