Transport of Mars atmospheric water into high northern latitudes during a polar warming [PDF]

Several numerical experiments were conducted with a simplified tracer transport model in order to attempt to examine the poleward transport of Mars atmospheric water during a polar warming like that which occurred during the winter solstice dust storm of

Multiscale energy conversion and transfer in the middle atmosphere during the 2023 sudden stratospheric warming

Earth and Planetary Physics
To understand energy transfer during sudden stratospheric warming (SSW) events in the middle atmosphere, the 2023 SSW is studied by using the analysis tools of the multiscale window transform (MWT) and MWT-based localized energetics analysis and theory ...

Lidar measurements of stratospheric aerosols over Menlo Park, California, October 1972 - March 1974 [PDF]

During an 18-month period, 30 nighttime observations of stratospheric aerosols were made using a ground based ruby lidar located near the Pacific coast of central California (37.5 deg. N, 122.2 deg. W). Vertical profiles of the lidar scattering ratio and
