An analysis of the collection 5 MODIS over-ocean aerosol optical depth product for its implication in aerosol assimilation
the collection 5 MODIS over-ocean aerosol optical depth product aerosol assimilation
2011/1/20
As an update to our previous use of the collection 4 Moderate Resolution Imaging Spectroradiometer (MODIS) over-ocean aerosol optical depth (AOD) data, we examined ten years of Terra and eight years o...
A decadal regional and global trend analysis of the aerosol optical depth using a data-assimilation grade over-water MODIS and Level 2 MISR aerosol products
the aerosol optical depth a data-assimilation grade over-water MODIS Level 2 MISR aerosol products
2010/11/30
Using the ten-year (2000–2009) Data-Assimilation (DA) quality Terra MODIS and MISR aerosol products, as well as 7 years of Aqua MODIS, we studied both regional and global aerosol trends over oceans. T...
Observation operator for the assimilation of aerosol type resolving satellite measurements into a chemical transport model
aerosol type satellite measurements a chemical transport model
2010/11/29
Modelling of aerosol particles with chemical transport models is still based mainly on static emission databases while episodic emissions cannot be treated sufficiently. To overcome this situation, a ...
Applying an ensemble Kalman filter to the assimilation of AERONET observations in a global aerosol transport model
Kalman filter assimilation AERONET observations global aerosol transport model
2010/3/16
We present a global aerosol assimilation system based on an Ensemble Kalman filter, which we believe leads to a significant improvement in aerosol fields. The ensemble allows realistic, spatially and ...
Impact of energetic particle precipitation on stratospheric polar constituents: an assessment using monitoring and assimilation of operational MIPAS data
energetic particle precipitation stratospheric polar constituents MIPAS
2010/2/21
In 2003, strong energetic particle precipitation (EPP) events occurred producing massive amounts of ionization which affected the polar region significantly perturbing its chemical state down to the m...
An operational system for the assimilation of the satellite information on wild-land fires for the needs of air quality modelling and forecasting
operational system satellite information wild-land fires
2009/9/23
This paper investigates a potential of two remotely sensed wild-land fire characteristics: 4-μm Brightness Temperature Anomaly (TA) and Fire Radiative Power (FRP) for the needs of operational chemical...
Implementation and testing of a simple data assimilation algorithm in the regional air pollution forecast model, DEOM
simple data assimilation algorithm regional air pollution forecast model DEOM
2009/8/7
A simple data assimilation algorithm based on statistical interpolation has been developed and coupled to a long-range chemistry transport model, the Danish Eulerian Operational Model (DEOM), applied ...
On the extraction of wind information from the assimilation of ozone profiles in Météo–France 4-D-Var operational NWP suite
wind information ozone profiles Météo–France 4-D-Var operational NWP suite
2009/7/23
By applying four-dimensional variational data-assimilation (4-D-Var) to a combined ozone and dynamics Numerical Weather Prediction model (NWP), ozone observations generate wind increments through the ...
PM10 data assimilation over Europe with the optimal interpolation method
PM10 data assimilation Europe optimal interpolation method
2009/3/12
This paper presents experiments of PM10 data assimilation with the optimal interpolation method. The observations are provided by BDQA (Base de Données sur la Qualité de l'Air), whose monitoring netwo...
Emergence of a tracer source from air concentration measurements, a new strategy for linear assimilation
air concentration measurements linear assimilation
2009/1/23
The measurement of atmospheric concentrations by a monitoring network is a promising tool for the identification of the widespread sources of trace species. The paper addresses the case of the species...
Data assimilation of stratospheric constituents: a review
Data assimilation stratospheric constituents review
2008/12/25
The data assimilation of stratospheric constituents is reviewed. Several data assimilation methods are introduced, with particular consideration to their application to stratospheric constituent measu...
Evaluating model performance of an ensemble-based chemical data assimilation system during INTEX-B field mission
