Derivation of PSC properties from ground based FTIR measurements at Kiruna (Sweden) on January 26 th, 2000
Polare stratosphärische Wolken (PSCs) spielen für die Ozonchemie der winterlichen Stratosphäre eine herausragende Rolle. Wechselwirkungen zwischen der abkühlenden Stratosphäre und der Existenz...
OVERVIEW OF MIPAS OPERATIONAL PRODUCTS (2007)
Raspollini, Piera, Aubertin, Ginette, Bartha, Sven, Birk, Manfred, Carli, Bruno, Carlotti, Massimo, ...
After 2 years of quasi continuously operations (from July 2002 to March 2004), MIPAS on ENVISAT was stopped due to problems in the mirror drive of the interferometer. Operations with reduced spectral...
Estimating cirrus cloud properties from MIPAS data (2007)
Mendrok, Jana, Schreier, Franz, Höpfner, Michael
High resolution mid-infrared limb emission spectra observed by the spaceborne Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) showing evidence of cloud interference are analyzed....

Sequential and Joint Retrieval of Trace Gas Profiles (2002)
Schwarz, Gottfried, Hilgers, Siegfried, Kemnitzer, Holger, Steck, Tilman, Clarmann Von, Thomas, Höpfner, Michael, ...
A purely sequential retrieval of trace gas profiles from limb sounding measurements may lead to error propagation, especially in the case of water vapor retrieval. A joint (i.e. simultaneous)...
Trace Gas Retrieval Including Horizontal Gradients (2002)
Kemnitzer, Holger, Hilgers, Siegfried, Schwarz, Gottfried, Steck, Tilman, Clarmann Von, Thomas, Höpfner, Michael, ...
Der Einfluss horizontaler Gradienten auf das Retrieval von Vertikalprofilen wird demonstriert und analysiert.
Experience Gained with the MIPAS Level 2 Off-Line Processor (2001)
Hilgers, Siegfried, Kemnitzer, Holger, Ressel, Klaus, Schwarz, Gottfried, Steck, Tilman, Clarmann Von, Thomas, ...
Performance tests of the MIPAS level 2 off-line processor led to in-depth experiences with retrieval options and performance characteristics. These depend on various parameters like microwindows,...
Trace Gas Retrieval Including Horizontal Gradients (2000)
Kemnitzer, Holger, Hilgers, Siegfried, Schwarz, Gottfried, Steck, Tilman, Clarmann Von, Thomas, Höpfner, Michael, ...
The results of trace gas retrievals of limb sounding measurements will be affected by a horizontally inhomogeneous atmosphere. In this case, the horizontal gradients should be included in the...
Sequential and Joint Retrieval of Trace Gas Profiles (2000)
Schwarz, Gottfried, Hilgers, Siegfried, Kemnitzer, Holger, Steck, Tilman, Clarmann Von, Thomas, Höpfner, Michael, ...
We demonstrate that a joint (i.e. simultaneous) retrieval of atmospherical trace gases from limb sounding measurements can outperform a purely sequential retrieval of the same trace gases. The reason...
Experience Gained with the MIPAS Level 2 Off-Line Processor (2000)
Hilgers, Siegfried, Kemnitzer, Holger, Ressel, Klaus, Schwarz, Gottfried, Steck, Tilman, Clarmann Von, Thomas, ...
The experience gained with the MIPAS level 2 offline processor will be described. In particular, the layout of the processor will be explained and results for various trace gas retrievals will be...
Optimized forward model and retrieval scheme for MIPAS near− real−time data processing (2000)
Marco Ridolfi, Bruno Carli, Massimo Carlotti, Thomas Von Clarmann, Bianca M. Dinelli, Anu Dudhia, ...
The infrared emission limb sounder MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) will be operated as an ESA core instrument on the ENVISAT-1 satellite. Near real time retrieval of...
