Multi-Decadal Aerosol Variations from 1980 to 2009: A Perspective from Observations and a Global Model [PDF]

, 2014
Aerosol variations and trends over different land and ocean regions during 1980-2009 are analyzed with the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model and observations from multiple satellite sensors and ground-based networks ...

Using Simulated Radiances to Understand the Limitations of Satellite‐Retrieved Volcanic Ash Data and the Implications for Volcanic Ash Cloud Forecasting

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 23, 16 December 2024.
Abstract Volcanic Ash Advisory Centers (VAACs) have generated volcanic ash forecasts for the aviation industry since the mid‐1990s. The excellent spatial and temporal coverage of satellite data makes them critical to the validation of ash dispersion model forecasts.

Volcanic sulfate deposition to Greenland and Antarctica: A modeling sensitivity study [PDF]

, 2013
Reconstructions of the atmospheric sulfate aerosol burdens resulting from past volcanic eruptions are based on ice core-derived estimates of volcanic sulfate deposition and the assumption that the two quantities are directly proportional.

Dynamics, Monitoring, and Forecasting of Tephra in the Atmosphere

Reviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Explosive volcanic eruptions inject hot mixtures of solid particles (tephra) and gasses into the atmosphere. Entraining ambient air, these mixtures can form plumes rising tens of kilometers until they spread laterally, forming umbrella clouds. While the largest clasts tend to settle in proximity to the volcano, the smallest fragments, commonly

Long‐Term Temperature Impacts of the Hunga Volcanic Eruption in the Stratosphere and Above

Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.
Abstract Global average upper atmosphere temperature changes linked with the Hunga volcanic eruption (January 2022) are analyzed based on satellite measurements and compared with chemistry‐climate model simulations. Results show stratospheric cooling of −0.5 to −1.0 K in the middle and upper stratosphere during 2022 through middle 2023, followed by ...

Evaluating the relationship between interannual variations in the Antarctic ozone hole and Southern Hemisphere surface climate in chemistry-climate models [PDF]

, 2019
Studies have recently reported statistically significant relationships between observed year-to-year spring Antarctic ozone variability and the Southern Hemisphere Annular Mode and surface temperatures in spring-summer.

Scale‐Dependent Drivers of Air‐Sea CO2 Flux Variability

Geophysical Research Letters, Volume 51, Issue 20, 28 October 2024.
Abstract In climate studies, it is crucial to distinguish between changes caused by natural variability and those resulting from external forcing. Here we use a suite of numerical experiments based on the ECCO‐Darwin ocean biogeochemistry model to separate the impact of the atmospheric carbon dioxide (CO2) growth rate and climate on the ocean carbon ...

Lidar measurements of stratospheric aerosol content and depolarization ratios after the eruption of El Chichón volcano: measurements at Nagoya, Japan

Geofísica Internacional, 1984
Después de la erupción de "El Chichón", se observó un enorme aumento en la dispersión de fondo de la luz desde la capa de aerosol estratosférico, utilizando un lidar de rubí en Nagoya, Japón (35ºN, 137ºW).En la parte inferior de la capa principal de ...
