Toth,Vl.G. Tyuterev,J. Vander Auwera,Prasad Varanasi,Georg Wagner +53 more
TL;DR: The GEISA database as discussed by the authors is a computer accessible spectroscopic database, designed to facilitate accurate forward radiative transfer calculations using a line-byline and layer-by-layer approach.

Armante,Blandine Barret,Claude Camy-Peyret,Jean-Pierre Chaboureau,Pierre-François Coheur,Laurent Crépeau,Gaëlle Dufour,Laurent C.-Labonnote,L.

TL;DR: In this paper, an improvement of spectral resolution and radiometric noise is proposed for the IASI-New Generation (IASI-NG) instrument, which has the potential for strongly benefiting the numerical weather prediction, chemistry and climate communities now connected through the European GMES/Copernicus initiative.
Journal ArticleDOI
Characterisation of dust aerosols in the infrared from IASI and comparison with PARASOL, MODIS, MISR, CALIOP, and AERONET observations
S. Peyridieu,S. Peyridieu,Alain Chédin,Virginie Capelle,Christoforos Tsamalis,Clémence Pierangelo,R. Armante,Cyril Crevoisier,Laurent Crépeau,Mathilde Siméon,F. Ducos,Noelle A. Scott +11 more
TL;DR: In this paper, the authors used Look-Up-Tables computed for a large selection of atmospheric situations and observing conditions to compare IASI-retrieved 10 μm AOD and total visible optical depth at 550 nm from either the MODIS/Aqua or the Multi-angle Imaging SpectroRadiometer (MISR) or the Polarization and Anisotropy of Reflectances for Atmospheric Science coupled with Observations from a Lidar (PARASOL).
Journal ArticleDOI
The 2007–2011 evolution of tropical methane in the mid-troposphere as seen from space by MetOp-A/IASI
Cyril Crevoisier,D. Nobileau,R. Armante,Laurent Crépeau,Toshinobu Machida,Yousuke Sawa,H. Matsueda,Tanja Schuck,T. Thonat,J. Pernin,Noelle A. Scott,Alain Chédin +11 more
TL;DR: IASI onboard MetOp-A provides a complete view of the geographical distribution, seasonality and long-term tendency of mid-troposphere methane in the mid- troposphere.

Virginie Capelle,Alain Chédin,Marc Pondrom,Mathilde Siméon,Christophe Tsamalis,Clémence Pierangelo,Raymond Armante,Cyril Crevoisier,Laurent Crépeau,N.A. Scott +9 more
TL;DR: In this paper, IASI-derived monthly mean infrared (10 μm) dust aerosol optical depth (AOD) and altitude are evaluated against ground-based Aerosol RObotic NETwork of sun photometers (AERONET) measurements of the 500 nm coarse-mode AOD and CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization).
