Assimilation of surface NO2 and O3 observations into the SILAM chemistry transport model
surface NO2 chemistry transport model
2015/3/5
This paper describes the assimilation of trace
gas observations into the chemistry transport model SILAM
(System for Integrated modeLling of Atmospheric coMposition) using the 3D-Var method. Assimil...
Assimilation of OMI NO2 retrievals into the limited-area chemistry-transport model DEHM (V2009.0) with a 3-D OI algorithm
OMI NO2 retrievals limited-area chemistry-transport model DEHM 3-D OI algorithm
2014/12/17
Data assimilation is the process of combining real-world observations with a modelled geophysical field. The increasing abundance of satellite retrievals of atmospheric trace gases makes chemical data...

The National Air Quality Forecast Capability (NAQFC) project provides the US with operational and experimental real-time ozone predictions using two different versions of the three-dimensional Communi...
Intercomparison of measurements of NO2 concentrations in the atmosphere simulation chamber SAPHIR during the NO3Comp campaign
NO2 concentrations atmosphere simulation chamber SAPHIR NO3Comp campaign
2010/2/8
NO2 concentrations were measured by various instruments during the NO3Comp campaign at the atmosphere simulation chamber SAPHIR at Forschungszentrum Jülich, Germany, in June 2007. Analytical methods i...
Relationship between the NO2 photolysis frequency and the solar global irradiance
Relationship NO2 photolysis frequency solar global irradiance
2010/2/8
Representative values of the atmospheric NO2 photolysis frequency j(NO2) are required for the adequate calculation and interpretation of NO and NO2 concentrations and exchange fluxes near the surface....
An improved tropospheric NO2 retrieval for OMI observations in the vicinity of mountainous terrain
tropospheric NO2 OMI observations vicinity mountainous terrain
2010/2/8
We present an approach to reduce topography-related errors of vertical tropospheric columns (VTC) of NO2 retrieved from the Ozone Monitoring Instrument (OMI) in the vicinity of mountainous terrain. Th...
