Age of stratospheric air in the ERA-Interim [PDF]
Atmospheric Chemistry and Physics, 2012 The Brewer-Dobson mean circulation and its variability are investigated in the ERA-Interim over the period 1989-2010 by using an off-line Lagrangian transport model driven by analysed winds and heating rates. <br><br> At low and mid-latitudes,

Kinetics of aging process on reduced Ag exchanged mordenite in dry air and humid air
AIChE Journal, 2020 Abstract Aging effects of off‐gas streams including dry air and humid air on reduced silver exchanged mordenite (Ag 0 Z) were studied. Aged Ag 0 Z was prepared by exposing Ag 0 Z to dry air and ...

Reassessment of MIPAS age of air trends and variability [PDF]
Atmospheric Chemistry and Physics, 2015 A new and improved setup of the SF6 retrieval together with a newly calibrated version of MIPAS-ENVISAT level 1b spectra (version 5, ESA data version 5.02/5.06) was used to obtain a new global SF6 data set, covering the total observational period of ...

Air Mixing in Firn and the Age of the Air at Pore Close-Off [PDF]
Annals of Glaciology, 1988 The air trapped in the bubbles of natural ice is not the same age as the surrounding ice. This is due to the fact that the air is enclosed in isolated bubbles only at the depth of the firn–ice transition. Within the overlying porous firn layer the air is able to mix and to exchange to a certain degree with the atmosphere. The age difference between ice

Effect of a System Air Conditioner on Local Air Quality in a Four-bed Ward
Aerosol and Air Quality Research, 2020 In a ward where many patients are hospitalized, effective ventilation is important because airborne viruses may cause secondary infection. This study investigates the changes in the air quality in a four-bed ward according to the use of a ventilation ...

Stratospheric age of air variations between 1600 and 2100
Geophysical Research Letters, 2016 The current understanding of preindustrial stratospheric age of air (AoA), its variability, and the potential natural forcing imprint on AoA is very limited.
