本文介绍了2009年更新的光谱数据库GEISA（Gestion et Etude des Informations Spectroscopiques Atmospheriques;大气光谱信息的管理和研究）。GEISA是一个计算机可访问的系统，包括三个独立的子数据库，分别用于：线参数、红外和紫外/可见光吸收截面、大气气溶胶的微物理和光学特性。在这个版本中，线参数子数据库中涉及50个分子，包括111个同位素体，总共3，807，997个条目，光谱范围从10（-6）到35，877.031厘米（-1）新一代高光谱探测器的成功性能最终取决于光学活性物质的光谱参数的准确性。大气气体是已知的，因为它们构成用于解释其观测的前向辐射传输模型的基本输入。目前，GEISA正在通过源自GEISA的GEISA/IASI数据库，参与与评估METOP欧洲卫星上IASI（红外大气探测干涉仪; http：//smsc.cnes.fr/lASI/index.htm）能力有关的活动。自Metop-A（http：//www.example.com）启动（2006年10月19日）以来，GEISA是验证第一级国际天文学空间干涉仪数据的参考光谱数据库。www.eumetsat.int此外，GEISA还参与行星研究，即，GEISA自1976年以来一直在LMD（法国动力气象学实验室）开发和维护，并在IPSL/CNRS（法国）“以太”产品和服务中心网站（http：//www.example.com）上实施，所有存档的光谱数据都可以通过通用和用户友好的相关管理软件设施进行处理。ether.ipsl.jussieu.fr 350多名研究人员注册在线使用GEISA。(C)2011爱思唯尔有限公司保留所有权利。
The updated 2009 edition of the spectroscopic database GEISA (Gestion et Etude des Informations Spectroscopiques Atmospheriques; Management and Study of Atmospheric Spectroscopic Information) is described in this paper. GEISA is a computer-accessible system comprising three independent sub-databases devoted, respectively, to: line parameters, infrared and ultraviolet/visible absorption cross-sections, microphysical and optical properties of atmospheric aerosols. In this edition, 50 molecules are involved in the line parameters sub-database, including 111 isotopologues, 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; http://smsc.cnes.fr/lASI/index.htm) on board the METOP European satellite through the GEISA/IASI database derived from GEISA. Since the Metop-A (http://www.eumetsat.int) launch (19 October 2006), GEISA is the reference spectroscopic database for the validation of the level-1 IASI data. Also, GEISA is involved in planetary research, i.e., modeling of Titan's atmosphere, in the comparison with observations performed by Voyager, or by ground-based telescopes, and by the instruments on board the Cassini-Huygens mission.GEISA, continuously developed and maintained at LMD (Laboratoire de Meteorologie Dynamique, France) since 1976, is implemented on the IPSL/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. (C) 2011 Elsevier Ltd. All rights reserved.
