Imaging spectrometry has the potential of remotely detecting atmospheric trace gases on the basis of their absorption of radiation. Ozone absorbs particulary in the ultraviolet and visible range of the spectrum, whereas water vapor has strong absorption features in the near infrared. Hence, spectrometry is expected to be a promising tool to extract these(More)
Egorov's theorem on the classical propagation of quantum observables is related to prominent quasi-classical descriptions of quantum molecular dynamics as the linearized semiclassical initial value representation, the Wigner phase space method, or the statistical quasiclassical method. The error estimates show that different accuracies are achievable for(More)
Imaging spectrometry has the potential of remotely detecting atmospheric trace gases on the basis of their absorption of radiation. Ozone absorbs particulary in the ultraviolet and visible range of the spectrum. Hence, spectrometry is expected to be a promising tool to extract the ozone contents in a given air column by using the correlation between(More)
Two methods for the measurement of the column water vapor in the atmosphere are compared with respect to their usefulness for imaging spectrometer campaigns. First, in situ measurements of 26 radiosonde launches are integrated with height to obtain the water vapor column. Second, simultaneous ground irradiance measurements using a sun photometer are(More)
Ich erkläre hiermit, dass ich die Master's Thesis selbständig und nur mit den angegebenen Hilfsmitteln angefertigt habe. Abstract In this thesis we study the quantum propagation of Heisenberg observables for the time-dependent semiclassical Schrödinger equation. We develop a numerical approximation for the evolution of expectation values of Weyl quantized(More)
