High resolution Whole Atmosphere Community Climate Model (WACCM) simulations are used to study how gravity waves vary during a stratospheric sudden warming (SSW) event from the source region to the lower thermosphere.

The NCAR Whole Atmosphere Community Climate Model (WACCM), with a quasi-uniform horizontal resolution of $\sim$25km and a vertical resolution of 0.1 scale height, produces large horizontal winds and vertical shears maximizing in the mesosphere and lower thermosphere (MLT), similar to those found

Optical lightning sensors like the Optical Transient Detector and Lightning Imaging Sensor (LIS) measure total lightning across large swaths of the globe with high detection efficiency.

At one meter, the Sunrise Balloon-Borne Stratospheric Solar Observatory is the largest solar telescope to leave the earth. Its aim during its June 12 to June 17, 2013 flight was to study the magneto-convective processes of the sun at a resolution of better than 100 km.

This paper investigates a possible physical mechanism of the observed dayside high-latitude upper thermospheric wind using numerical simulations from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model.

The Interface Region Imaging Spectrograph (IRIS) provides an unparalleled opportunity to explore the (thermal) interface between the chromosphere, transition region, and the coronal plasma observed by the Atmospheric Imaging Assembly (AIA) of the Solar Dynamics Observatory (SDO).
