8 The Stellar Occultation Measurement Principle Download Scientific A stellar occultation constellation configuration was designed based on the simulation results, and the results showed that the following parameters of satellites can be used to realize the global. An overview of the gomos instrument and highlights of the measurements are given in bertaux et al. (2010) the stellar occultation technique shares the main advan tages of the solar occultation.
Principle And Geometry Of The Gomos Stellar Occultation Measurements Fig. 1. the principle of the stellar occultation measurement. the measurements above the atmosphere are used to build up the ref erence spectrum for the star. the measurements through the at mosphere are used to calculate the horizontal transmission spectra. these serve as a starting point for geophysical retrieval. 200 300 400 500 600 700 800. The principle of stellar occultation is illustrated in fig. 2. gomos is implemented on envisat opposite to the ve locity vector and looks at various stars while the platform is moving occultation. Gomos instrument and highlights of the measurements are given in bertaux et al. (2010) the stellar occultation technique shares the main advan tages of the solar occultation technique that include the self calibrated measurement principle (see fig. 1), relatively sim ple inverse problem, and high vertical resolution. in addition,. The stellar occultation technique 265 on the measurements was first proposed by hays and roble (1968). roble favored stellar occultations over solar occultations, which have been the primary occultation method of studying the earth's lower atmosphere, for a number of reasons.
