The possible effects of El Chichon eruption on atmospheric thermal and chemical structure and surface climate

Geofísica Internacional, 1984
Se sugiere que la inyección de óxidos de azufre y ceniza en la estratosfera desde la erupción de 1982 de El Chichón, alteraría el equilibrio radiativo-fotoquímico de la atmósfera de la Tierra, lo cual a su vez conduciría a los cambios en la temperatura ...

Influence of the El Chichon eruption on the stratosphere after summer 1982

Geofísica Internacional, 1984
En Quiroz (1983) se atribuyó un calentamiento de 1 - 3° a 30 mb, entre los 3SºN y el ecuador, a la erupción de El Chichón para el verano de 1982. Dos interrogantes se consideran aquí, una posible influencia' de este calentamiento sobre la oscilación ...

First ice core records of NO3− stable isotopes from Lomonosovfonna, Svalbard [PDF]

, 2014
Samples from two ice cores drilled at Lomonosovfonna, Svalbard, covering the period 1957–2009, and 1650–1995, respectively, were analyzed for NO3− concentrations, and NO3− stable isotopes (δ15N and δ18O).

Evidence for changes in stratospheric transport and mixing over the past three decades based on multiple data sets and tropical leaky pipe analysis [PDF]

, 2010
Variability in the strength of the stratospheric Lagrangian mean meridional or Brewer-Dobson circulation and horizontal mixing into the tropics over the past three decades are examined using observations of stratospheric mean age of air and ozone. We use
