An approach to retrieve information on the carbonyl fluoride (COF2) vertical distributions above Jungfraujoch by FTIR multi-spectrum multi-window fitting
carbonyl fluoride (COF2) vertical distributions Jungfraujoch FTIR multi-spectrum multi-window fitting
2009/12/3
We present an original multi-spectrum fitting procedure to retrieve volume mixing ratio (VMR) profiles of carbonyl fluoride (COF2) from ground-based high resolution Fourier transform infrared (FTIR) s...
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...
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 ...
Refinements in the use of equivalent latitude for assimilating sporadic inhomogeneous stratospheric tracer observations，2：Precise altitude-resolved information about transport of Pinatubo aerosol to very high latitude
quivalent latitude sporadic inhomogeneous stratospheric tracer altitude-resolved Pinatubo aerosol
2009/3/5
From high latitude lidar observations, quite precise information is extracted about the temporal evolution and vertical distribution of volcanic aerosol in the high latitude lower stratosphere followi...

Elimination of hidden a priori information from remotely sensed profile data
information remotely sensed profile data
2008/11/28
Profiles of atmospheric state variables retrieved from remote measurements often contain a priori information which causes complication in the statistical use of data and in the comparison with other ...
Retrieval of stratospheric aerosol size information from OSIRIS limb scattered sunlight spectra
stratospheric aerosol size OSIRIS scattered sunlight spectra
2008/11/25
Recent work has shown that the retrieval of stratospheric aerosol vertical profiles is possible using limb scattered sunlight measurements at optical wavelengths. The aerosol number density profile is...
Information on the early Holocene climate constrains the summer sea ice projections for the 21st century
holocene climate ice projections
2008/11/7
The summer sea ice extent strongly decreased in the Arctic over the last decades. This decline is very likely to continue in the future but uncertainty of projections is very large. An ensemble of exp...
