Assimilation of infrared limb radiances from MIPAS in the ECMWF 4DVAR system
نویسنده
چکیده
MIPAS is a very high spectral resolution sounder (0.025 cm wavenumber resolution) onboard ESA's Envisat satellite. It provides 59,605 spectral points or channels in 5 bands in the range 685-2410 cm. In the nominal scanning configuration, it gives one scan about every 5o latitude for 17 tangent altitudes between 6 and 68 km. The field of view (FOV) is 3 km in the vertical and 30 km in the horizontal.

RTMIPAS: A fast radiative transfer model for the assimilation of infrared limb radiances from MIPAS
An RTTOV-type fast radiative transfer model has been developed for emitted clear-sky limb radiances from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) onboard ESA's Envisat. MIPAS is an infrared sounder with very high spectral resolution (0.025 cm, Table 1). It is designed to provide information on the thermal structure and chemical composition of the upper troposphere t...
متن کاملTowards Assimilating Infrared Limb Radiances from Mipas in the Ecmwf System
A new fast radiative transfer model to compute infrared limb radiances for the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) has been developed and validated, and a first application is presented. The model, referred to as RTMIPAS, can simulate radiances for all channels of the high-spectral resolution MIPAS instrument in the 685-2000 cm 1 wavenumber region. RTMIPAS is part ...

2. COMPARISON BETWEEN THE ECMWF 3DVAR AND 4DVAR SYSTEMS The ECMWF 4dVar system is, from the technical point of view, very similar to the 3dVar system. Both systems use the same unix scripts, and share much of the Fortran code. The same background error covariance matrix and observation operators are used, and most of the peripheral tasks such as fetching and archiving of fields and observations...
متن کاملGeophysical validation of temperature retrieved by the ESA processor from MIPAS/ENVISAT atmospheric limb-emission measurements
The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) has been operating since March 2002 onboard of the ENVIronmental SATellite of the European Space Agency (ESA). The high resolution (0.035 cm−1 full width half maximum, unapodized) limb-emission measurements acquired by MIPAS in the first two years of operation have very good geographical and temporal coverage and have been re...
متن کاملImplementation of 1D+4D-Var Assimilation of Precipitation Affected Microwave Radiances at ECMWF, Part I: 1D-Var
This paper presents the operational implementation of a 1D+4D-Var assimilation system of rain affected satellite observations at ECMWF. The first part describes the methodology and performance analysis of the 1D-Var retrieval scheme in clouds and precipitation that uses SSM/I microwave radiance observations for the estimation of total column water vapor. The second part shows the global and lon...
