3D-Druck und Montage des JetMobils, lower than 10 pptv most of the time. In addition a diurnal variation in the mixing ratios of NO. was found with higher daytime values than at night, 84 ± 49 pptv NO. overall and 37 ± 6 pptv NO. at night.

https://doi.org/10.1007/978-3-658-38661-0ed. For deter-ming actual values and profiles these methods are applicable to field measurements obtained from instrumented towers or boundary layer soundings. The theoretical concept is general enough to enable numerical evaluations at variable stability conditions in the atmosphere.

Studies in Computational Intelligenced Lehmann 1981) that at present enough information is available allowing reliable meteorological applications. In this paper two processes, the settlement of particles through the atmosphere under the influence of gravity and the activation of particles in fog and clouds, are considered.

Neutron-Induced Transmutation and ActivationParticle Induced x-Ray Emission (PIXE) has been used for the analysis of the elemental particle size distributions of the tropospheric aerosol and its elemental composition as a function of altitude. Data obtained for the first time in these studies will be discussed.

The Determination of Absorptive Properties of Atmospheric Aerosol Particles Using Photoacoustic SpecChopped light produces an acoustic signal in a closed cell when it is absorbed by a sample of material within this cell. This effect is used to develop a method for measuring the absorption coefficient of aerosol particles. The possibilities and limits of the method are discussed.

Measurements of Reduced Sulfur Gases in the Atmosphere few measurements of the gases..We have established a method for preconcentration and subsequent gas chromatographic and flame photometric analysis of reduced sulfur gases from the atmosphere. First measurements in environments of various degrees of pollution are reported. On a cruise across the Atl
