Impact of West African Monsoon convective transport and lightning NOx production upon the upper tropospheric composition: a multi-model study
West African Monsoon NOx production the upper tropospheric composition a multi-model study
2010/8/13
Within the African Monsoon Multidisciplinary Analysis (AMMA), we investigate the impact of nitrogen oxides produced by lightning (LiNOx) and convective transport during the West African Monsoon (WAM) ...
Lightning NOx emissions over the USA constrained by TES ozone observations and the GEOS-Chem model
Lightning NOx TES ozone observations GEOS-Chem model
2010/1/18
Improved estimates of NOx from lightning sources are required to understand tropospheric NOx and ozone distributions, the oxidising capacity of the troposphere and corresponding feedbacks between chem...
The effects of lightning-produced NOx and its vertical distribution on atmospheric chemistry: sensitivity simulations with MATCH-MPIC
lightning-produced NOx vertical distribution atmospheric chemistry MATCH-MPIC
2009/2/12
The impact of different assumptions concerning the source magnitude as well as the vertical placement of lightning-produced nitrogen oxides is studied using the global chemistry transport model MATCH-...
Estimating the NOx produced by lightning from GOME and NLDN data: a case study in the Gulf of Mexico

2009/1/5
Nitrogen oxides (NOxNO+NO2) play an important role in tropospheric chemistry, in particular in catalytic ozone production. Lightning provides a natural source of nitrogen oxides, dominating the produc...
Lightning and convection parameterisations – uncertainties in global modelling
Lightning convection parameterisations global modelling
2008/12/18
The simulation of convection, lightning and consequent NOx emissions with global atmospheric chemistry models is associated with large uncertainties since these processes are heavily parameterised. Ea...
The knowledge of the lightning-induced nitrogen oxides (LNOx) source is important for understanding and predicting the nitrogen oxides and ozone distributions in the troposphere and their trends, the ...
Lightning-produced NOx over Brazil during TROCCINOX: airborne measurements in tropical and subtropical thunderstorms and the importance of mesoscale convective systems
NOx Brazil airborne measurements subtropical thunderstorms mesoscale convective systems
2008/12/11
During the TROCCINOX field experiments in February–March 2004 and February 2005, airborne in situ measurements of NO, NOy, CO, and O3 mixing ratios and the J(NO2) photolysis rate were carried out in t...
The Chisholm firestorm: observed microstructure, precipitation and lightning activity of a pyro-cumulonimbus
observed microstructure pyro-cumulonimbus
2008/12/1
A fire storm that occurred on 28 May 2001 and devastated the town of Chisholm, ~150 km north of Edmonton, Alberta, induced a violent fire-invigorated cumulonimbus cloud. This pyro-cumulonimbus (pyro-C...
