The HITRAN molecular spectroscopic database: Edition of 2000 including updates through 2001

This paper describes the status circa 2001, of the HITRAN compilation that comprises the public edition available through 2001. The HITRAN compilation consists of several components useful for radiative transfer calculation codes: high-resolution spectroscopic parameters of molecules in the gas phase, absorption cross-sections for molecules with very dense spectral features, aerosol refractive indices, ultraviolet line-by-line parameters and absorption cross-sections, and associated database management software. The line-by-line portion of the database contains spectroscopic parameters for 38 molecules and their isotopologues and isotopomers suitable for calculating atmospheric transmission and radiance properties. Many more molecular species are presented in the infrared cross-section data than in the previous edition, especially the chlorofluorocarbons and their replacement gases. There is now sufficient representation so that quasi-quantitative simulations can be obtained with the standard radiance codes. In addition to the description and justification of new or modified data that have been incorporated since the last edition of HITRAN (1996), future modifications are indicated for cases considered to have a significant impact on remote-sensing experiments. © 2003 Elsevier Ltd.

The Promotion of 'SYMMETRICAL' European Citizenship: A Federal Perspective

This paper contributes to the ongoing debate about symmetrical citizenship at the European level by searching out new areas for consideration, in particular the judicial politics of European citizenship. Using a federal comparative perspective, it sheds light on the potential role the European Court of Justice (ECJ) could play in promoting symmetrical citizenship through the comparison with the experience of the early United States and of its Supreme Court. This paper proceeds to discuss why the ECJ has not acted in a way similar to that of the US Supreme Court, and concludes by offering some recommendations for a possible role of the ECJ as a critical agent in the promotion of Union citizenship beyond the economic sphere.
