Human-caused stratospheric cooling may have been detectable as early as 1885
A small, multi-institutional team of climate scientists has found evidence that human-caused impacts on the stratosphere began earlier than previously thought. In their study, published in the Proceedings of the National Academy of Sciences, the group used observational data, environmental theory and computer modeling to create simulations depicting the state of the stratosphere to a time just after the dawn of the industrial age.

A composite of the effects of major sudden stratospheric warming events on carbon dioxide radiative cooling in the mesosphere-lower-thermosphere
The major sudden stratospheric warming (SSW) events strongly influence the mean structure of the entire atmosphere, from the troposphere to the thermosphere. These events disrupt the compositional and thermal structure of the mesosphere and lower thermosphere (MLT), causing spatiotemporal variations in the concentration of trace species of this region. Currently, the role of dynamical changes during SSW events on radiative cooling in the MLT region is not well understood. An investigation of th…

Expansion Signatures in 35 HII Regions traced by SOFIA [CII] Emission
We analyze the expansion signatures of 35 HII regions mapped in [CII] 158 micron emission by the Stratospheric Observatory for Infrared Astronomy (SOFIA). The [CII] emission primarily traces photodissociation regions (PDRs) at the transition between ionized and neutral gas. The brightness and narrow linewidth of [C II] allow us to measure PDR expansion. Bubble-shaped regions often exhibit expansion, while irregular-shaped ones are less likely to. Of the 35 HII regions, 12 (~34%) exhibit clear e…
