Tsinghua SIGS developed satellite-based carbon emission inversion techniques to investigate the driving forces of global wildfire emission trends
SHENZHEN, China, Oct. 18, 2021 /PRNewswire-AsiaNet/ --

Zheng Bo's team at the Institute of Environment and Ecology, Tsinghua Shenzhen 
International Graduate School (SIGS), has developed a novel atmospheric 
inversion system to infer global wildfire carbon emissions from satellite 
retrievals of carbon monoxide, investigated the spatial and temporal trends and 
driving forces of global wildfire CO2 emissions from 2000-2019. Their study 
suggests that the absence of a rapid, contemporary decline in global wildfire 
emissions with burned area is the increasing forest wildfire emissions. This 
study can guide the future development of a global carbon budget monitoring and 
inversion framework based on satellite remote sensing. Dr. Zheng's research 
article, " Increasing forest fire emissions despite the decline in global 
burned area," has been published in Science Advances on 24th Sep 
(https://www.science.org/doi/10.1126/sciadv.abh2646). 

Satellites have detected a global decline in fire burned areas over grasslands, 
coincident with a small increase over forests over the past decades. Bo Zheng 
and his colleagues developed an atmospheric inversion system to show that 
global fire emissions have been stable or slightly decreasing despite the 
substantial decline in global burned area since 2000, caused by emission 
increase from forest fires offsetting the decreasing emissions from grass and 
shrubland fires. Forest fires are larger CO2 sources per unit area burned than 
grassland fires, with a slow or incomplete follow-up recovery — sometimes no 
recovery due to degradation and deforestation. With fires expanding over forest 
areas, the slow recovery of CO2 uptake over burned forest lands weakens land 
sink capacity, implying that pressures from global fires on climate have not 
been relieved despite the decline in global burned area.
