Note: The content of volatile-extracts is difficult to measure accurately. However, the fuels have high fatty-extracts always have high volatile-extracts at the same time, for example: conifers, eucalyptus.
High fire intensity and more emission, especially black carbon

Satellites development trends in China
⚫GF-5, GF-6,GF-7
⚫A number of geo-science satellites and
small satellites
FY-4A, Dec 11, 2016
By 2020, planned to
launch:
⚫FY 4B, FY-3F, FY-
4C, FY-RM2, FY-3G,
FY-4M

Conclusions
➢Chinese satellites have been important part of the fire
management. FY,HJ,GF series and other satellites did good job on
fire detection, monitoring, burned area mapping, etc.
➢However improvements are needed in, such as, spectrum
resolution and analysis technologies to increase the capacities of
detecting fuel extract contents and the impacts on heat release and
fire emission.
➢Conduct more comparisons between FY and other satellites,
such as Terra and Aqua, and produce more fire products from FY.
