It has been known for at least 30 years that vertically narrow thermal layers form within the
middle atmosphere. Two types of temperature enhancements, the low‐latitude to midlatitude …

An active topic of current research in aeronomy is the study of the dynamics of the
mesosphere and lower thermosphere (MLT) from 60 to 130 km, especially in regard to the …

Temperatures acquired by the Cryogenic Infrared Spectrometers and Telescopes for the
Atmosphere (CRISTA) during shuttle mission STS-66 have provided measurements of …

ABSTRACT The GPS/MET (Global Positioning System/Meteorology, Ware et al. 1996)
project demonstrated atmospheric limb sounding from low-earth orbit (LEO) with high …

Reanalysis data are used to evaluate the evolution of polar vortex geometry, planetary wave
drag, and gravity wave drag prior to split versus displacement sudden stratospheric …

We use temperature retrievals from the Constellation Observing System for Meteorology,
Ionosphere and Climate (COSMIC)/Formosa Satellite Mission 3 (FORMOSAT‐3) and …

Large-amplitude internal gravity waves were observed using Rayleigh lidar temperature
soundings above Rio Grande, Argentina (54∘ S, 68∘ W), in the period 16–23 June 2018 …

Sudden stratospheric warmings (SSWs) are circulation anomalies in the polar region during
winter. They mostly occur in the Northern Hemisphere and affect also surface weather and …

A new Cloud Imaging and Particle Size (CIPS) gravity wave (GW) variance data set is
available that facilitates automated analysis of GWs entering the mesosphere. This work …

Abstract Five years of Fe Boltzmann lidar's Rayleigh temperature data from 2011 to 2015 at
McMurdo are used to characterize gravity wave potential energy mass density (Epm) …
