Abstract

International audience; Remote sensing of aerosol properties in the visible domain has been widely used for a better characterization of these particles and of their effect on solar radiation. On the opposite, remote sensing of aerosols in the thermal infrared domain still remains marginal. However, knowledge of the effect of aerosols on terrestrial radiation is needed for the evaluation of their total radiative forcing. A key point of infrared remote sensing is its ability to retrieve aerosol optical depth as well as mean dust layer altitude, a variable required for measuring their impact on climate. Moreover, observations are possible night and day, over ocean and over land. Our algorithm is specifically designed to retrieve simultaneously coarse mode dust aerosol 10 µm optical depth (AOD) and mean layer altitude from high spectral resolution infrared sounders observations. In this context, results obtained from 6 years (2003-2008) of AIRS observations have been compared to other aerosol sensors on the A-Train. First, our AIRS-retrieved 10 µm dust optical depth shows a very good agreement with the 0.55 µm Aqua/MODIS optical depth product, particularly for tropical Atlantic regions downwind of the Sahara during the dust season, even far from the sources. Comparisons with PARASOL non-spherical coarse mode product confirm the agreement found between AIRS and other AOD products from A-Train instruments. Second, time series of the mean aerosol layer altitude are compared to the CALIOP Level-2 products starting June 2006. For regions located downwind of the Sahara, the comparison again shows a good agreement with a mean standard deviation between the two products of about 400 m over the period processed, demonstrating that our algorithm effectively allows retrieving accurate mean dust layer altitude. A 6-year global climatology of the aerosol 10 µm dust optical depth and of the layer mean altitude has also been established, emphasizing the natural cycles of Saharan dust. This algorithm has been designed for processing high spectral resolution infrared sounders in general and is now applied to IASI observations. Thanks to IASI higher spectral resolution, the selection of finer channels for aerosol detection allows an even more accurate determination of aerosol properties. Results obtained from the first year of IASI observations will be presented and compared to other aerosol products and measurements.

Abstract

The updated 2009 edition of GEISA1 (Gestion et Etude des Informations Spectroscopiques Atmosphriques; Management and Study of Atmospheric Spectroscopic Information), a computer-accessible system comprising three independent sub-databases devoted respectively to: line transition parameters, infrared and ultraviolet/visible absorption cross-sections, microphysical and optical properties of atmospheric aerosols will be summarized. In this edition, 50 molecules are involved in the line transition parameters sub-database, including 111 isotopes, for a total of 3,807,997 entries, in the spectral range from 10−6 to 35,877.031 cm−1. The successful performances of the new generation of hyperspectral sounders depend ultimately on the accuracy to which the spectroscopic parameters of the optically active atmospheric gases are known, since they constitute an essential input to the forward radiative transfer models that are used to interpret their observations. Currently, GEISA is involved in activities related to the assessment of the capabilities of IASI (Infrared Atmospheric Sounding Interferometer on board the METOP European satellite http://earthsciences. cnes.fr/IASI) through the GEISA/IASI database2 derived from GEISA. Since the Metop (http://www.eumetsat.int) launch (October 19th 2006), GEISA/IASI is the reference spectroscopic database for the validation of the level-1 IASI data, using the 4A radiative transfer model3 (4A/LMD http://ara.lmd.polytechnique.fr; 4A/OP codeveloped by LMD and Noveltis http://www.noveltis.fr, with the support of CNES). Also, GEISA is involved in planetary research, i.e.: modelling of Titans atmosphere, in the comparison with observations performed by Voyager, or by ground-based telescopes, and by the instruments on board the Cassini-Huygens mission. Highlights will be given on a selection of problems that pertains to current status of the line parameters affecting IASI hyperspectral remote sensing applications. A special effort has been given in the validation of the updated parameters and the evaluation of the subsequent impact on radiative transfer simulations. Results of comparisons ”calcobs” based on IASI observations and 4AOP simulations will be presented. GEISA, continuously developed and maintained at LMD (Laboratoire de M´et´eorologie Dynamique, France) since 1976, is implemented on the CNES/CNRS (France) ”Ether” Products and Services Centre WEB site (http://ether.ipsl.jussieu.fr), where all archived spectroscopic data can be handled through general and user friendly associated management software facilities. More than 350 researchers are registered for on line use of GEISA.

Abstract

International audience; The development of Gestion et Etude des Informations Spectroscopiques Atmosphériques (GEISA: Management and Study of Spectroscopic Information) was started over three decades at Laboratoire de Météorologie Dynamique (LMD) in France. GEISA is a computer accessible spectroscopic database, designed to facilitate accurate forward radiative transfer calculations using a line-by-line and layer-by-layer approach. More than 350 users have been registered for on-line use of the GEISA facilities. The current 2003 edition of GEISA (GEISA-03) is a system comprising three independent sub-databases devoted respectively to: line transition parameters, infrared and ultraviolet/visible absorption cross-sections, microphysical and optical properties of atmospheric aerosols.Currently, GEISA is involved in activities related to the assessment of the capabilities of IASI (Infrared Atmospheric Sounding Interferometer on board of the METOP European satellite) through the GEISA/IASI database derived from GEISA.The GEISA-03 content is presented, placing emphasis on molecular species of interest for Earth and planetary atmosphere studies, with details on the updated 2008 archive underway. A critical assessment on the needs, in terms of molecular parameters archive, related with recent satellite astrophysical missions is made. Detailed information on free on-line GEISA and GEISA/IASI access is given at http://ara.lmd.polytechnique.fr and http://ether.ipsl.jussieu.fr.
