Geophysical Research Letters, doi:https://doi.org/10.1029/2024GL109757 Time series of radiative cooling of the upper mesosphere and lower thermosphere (UMLT) by carbon dioxide (CO2) are examined for evidence of trends over 20 years. Radiative cooling rates in K day-1 provided by the SABER instrument are conver... ACOM Affiliations: MODELING Publication Genre: Article View on OpenSky |

High temperature sensitivity of Arctic isoprene emissions explained by sedges Wang, H., Welch, A. M., Nagalingam, S., Leong, C., Czimczik, C. I., et al. (2024). High temperature sensitivity of Arctic isoprene emissions explained by sedges. Nature Communications, doi:https://doi.org/10.1038/s41467-024-49960-0 It has been widely reported that isoprene emissions from the Arctic ecosystem have a strong temperature response. Here we identify sedges (Carex spp. and Eriophorum spp.) as key contributors to this high sensitivity using plant chamber expe... ACOM Affiliations: ESS Publication Genre: Article View on OpenSky |

Ma, C., Su, H., Lelieveld, J., Randel, W., Yu, P., et al. (2024). Smoke-charged vortex doubles hemispheric aerosol in the middle stratosphere and buffers ozone depletion. Science Advances, doi:https://doi.org/10.1126/sciadv.adn3657 Australian mega-wildfires in the summer of 2019-2020 injected smoke into the stratosphere, causing strong ozone depletion in the lower stratosphere. Here, we model the smoke plume and reproduce its unexpected trajectory toward the middle st... ACOM Affiliations: ACRESP Publication Genre: Article View on OpenSky |
