Algorithm for Retrieval of Temperature in Mesosphere and Lower Thermosphere from O2 A-Band Night Glow
نویسندگان
چکیده
The O2 A-band night glow can be used to retrieve the temperature in range of 80–120 km mesosphere and lower thermosphere (MLT). From full spectrum glow, band is selected based on sensitivity emission line temperature, taking into account compromise relationship between spectral resolution, inversion efficiency, accuracy. non-linear iterative method optimization theory adopted for retrieval temperature. Meanwhile, considering stability inversion, Tikhonov regularization matrix added as a constraint, optimal estimation algorithm optimized suppress influence measurement noise results. Through recovering simulated noisy spectra from an interferometer, profile with vertical resolution better than 2 average accuracy K obtained by this paper. In addition, priori constraints studied, limits When controlled within ±5 K, 1.35 which OSIRIS Odin at 90–105 km.

Retrieval of nitric oxide in the mesosphere and lower thermosphere from SCIAMACHY limb spectra
We use the ultra-violet (UV) spectra in the range 230–300 nm from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) to retrieve the nitric oxide (NO) number densities from atmospheric emissions in the gamma-bands in the mesosphere and lower thermosphere. Using 3-D ray tracing, a 2-D retrieval grid, and regularisation with respect to altitude and latitude, we ...
متن کاملSilicon chemistry in the mesosphere and lower thermosphere
Silicon is one of the most abundant elements in cosmic dust, and meteoric ablation injects a significant amount of Si into the atmosphere above 80 km. In this study, a new model for silicon chemistry in the mesosphere/lower thermosphere is described, based on recent laboratory kinetic studies of Si, SiO, SiO2, and Si+. Electronic structure calculations and statistical rate theory are used to sh...
