Horizontal and vertical transports of biomass fire emissions
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract During the Northern hemisphere winter season, biomass burning is widespread in West Africa, yet the total tropospheric column ozone values (<30 DU) over much of the Tropical Atlantic Ocean (15 • N–5 • S) are relatively low. At the same time, the tro-posph...
متن کاملBiomass burning emissions estimated with a global fire assimilation system based on observed fire radiative power
The Global Fire Assimilation System (GFASv1.0) calculates biomass burning emissions by assimilating Fire Radiative Power (FRP) observations from the MODIS instruments onboard the Terra and Aqua satellites. It corrects for gaps in the observations, which are mostly due to cloud cover, and filters spurious FRP observations of volcanoes, gas flares and other industrial activity. The combustion rat...
متن کاملVertical mixing of commercial aviation emissions from cruise altitude to the surface
[1] Data analysis and numerical simulations were used to examine vertical transport of cruise‐altitude commercial aircraft emissions to the surface. First, aircraft emission data were compared with static stability and potential temperature data from satellites. Second, we ran global 3‐D simulations of a passive tracer released uniformly at 11 km (cruise altitude). We present global, regional, ...
متن کاملVariability of vegetation fire emissions
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Biomass burning has long been recognised as an important source of trace gases and aerosols in the atmosphere. The burning of vegetation has a repeating seasonal pattern, but the intensity of burning and the exact localisation of fires vary considerably f...
