The aim of this paper is to compare a number of radiative transfer models for atmospheric sounding in the millimeter and sub-millimeter wavelength range and to check their consistency and mutual deviations. This inter-comparison deals with three different aspects of the radiative transfer models: (1) The inherent physics of gaseous absorption lines and how(More)
Because of the effect of defocusing and incomplete overlap between the laser beam and the receiver field of view, elastic lidar systems are unable to fully capture the close-range backscatter signal. Here we propose a method to empirically estimate and correct such effects, allowing to retrieve the lidar signal in the region of incomplete overlap. The(More)
The European Centre for Medium-Range Weather Forecasts (ECMWF) provides global analyses of atmospheric humidity from the ground to the lower mesosphere. Unlike in the troposphere, in the stratosphere no humidity observations are assimilated. Humidity analyses here are essentially the results of a free-running model constrained by the ECMWF's analysed wind(More)
The STARTWAVE (STudies in Atmospheric Radiative Transfer and Water Vapour Effects) project aims to investigate the role which water vapour plays in the climate system , and in particular its interaction with radiation. Within this framework, an ongoing water vapour database project was set up which comprises integrated water vapour 5 (IWV) measurements made(More)
Water vapour has been measured from the International Scientific Station Jungfraujochcrowave radiometry and Raman lidar. The abundance of atmospheric water vapour between the planetary boundary layer and the upper stratosphere varies over more than 5 three orders of magnitude. The currently used measurement techniques are suited to determine the abundance(More)
This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Estimates of the natural CO 2 flux over Europe inferred from in situ measurements of atmospheric CO 2 mole fraction have been used previously to check top-down flux estimates(More)
