Simulating Southern Ocean aerosol and ice nucleating particles in the Community Earth System Model version 2

McCluskey, C. S., Gettelman, A., Bardeen, C., DeMott, P. J., Moore, K. A., et al. (2023). Simulating Southern Ocean aerosol and ice nucleating particles in the Community Earth System Model version 2. Journal of Geophysical Research: Atmospheres, doi:https://doi.org/10.1029/2022JD036955

Southern Ocean (SO) low-level mixed phase clouds have been a long-standing challenge for Earth system models to accurately represent. While improvements to the Community Earth System Model version 2 (CESM2) resulted in increased supercooled...

Stratospheric water vapor from the Hunga Tonga-Hunga Ha'apai volcanic eruption deduced from COSMIC-2 radio occultation

Randel, W., Johnston, B. R., Braun, J. J., Sokolovskiy, S., Vömel, H., et al. (2023). Stratospheric water vapor from the Hunga Tonga-Hunga Ha'apai volcanic eruption deduced from COSMIC-2 radio occultation. Remote Sensing, doi:https://doi.org/10.3390/rs15082167

The eruption of the Hunga Tonga–Hunga Ha'apai (HTHH) volcano on 15 January 2022 injected large amounts of water vapor (H2O) directly into the stratosphere. While normal background levels of stratospheric H2O are not detectable in radio occu...

A new algorithm to generate a priori trace gas profiles for the GGG2020 retrieval algorithm

Laughner, J. L., Roche, S., Kiel, M., Toon, G. C., Wunch, D., et al. (2023). A new algorithm to generate a priori trace gas profiles for the GGG2020 retrieval algorithm. Atmospheric Measurement Techniques, doi:https://doi.org/10.5194/amt-16-1121-2023

Optimal estimation retrievals of trace gas total columns require prior vertical profiles of the gases retrieved to drive the forward model and ensure the retrieval problem is mathematically well posed. For well-mixed gases, it is possible t...
