Климатическая изменчивость стратосферно-тропосферных взаимодействий, наблюдаемая в последние десятилетия

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2021
В данной работе показано, как изменялось взаимодействие между тропосферой и стратосферой в последние десятилетия. Также оценено влияние таких явлений, как квазидвухлетнее колебание (КДК) на данное взаимодействие.

In-situ comparison of the NOy instruments flown in MOZAIC and SPURT [PDF]

open access: yes, 2006
Two aircraft instruments for the measurement of total odd nitrogen (NOy) were compared side by side aboard a Learjet A35 in April 2003 during a campaign of the AFO2000 project SPURT (Spurengastransport in der Tropopausenregion).

Tropospheric Ozone at Northern Mid-Latitudes: Modeled and Measured Long-Term Changes

open access: yesAtmosphere, 2017
In this paper, we investigate why current state-of-the-art chemistry-climate models underestimate the tropospheric ozone increase from the 1950s to the 1990s by approximately 50%.

Contribution of mixing to upward transport across the tropical tropopause layer (TTL) [PDF]

open access: yes, 2006
During the second part of the TROCCINOX campaign that took place in Brazil in early 2005, chemical species were measured on-board the high-altitude research aircraft Geophysica (ozone, water vapor, NO, NOy, CH4 and CO) in the altitude range up to 20 km ...

CARIBIC observations of gaseous mercury in the upper troposphere and lower stratosphere

open access: yesE3S Web of Conferences, 2013
A unique set of gaseous mercury measurements in the upper troposphere and lower stratosphere (UT/LS) has been obtained during the monthly CARIBIC (www.caribic-atmospheric.com) flights since May 2005.

Investigation of the α-pinene photooxidation by OH in the atmospheric simulation chamber SAPHIR [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
The photooxidation of the most abundant monoterpene, α-pinene, by the hydroxyl radical (OH) was investigated at atmospheric concentrations in the atmospheric simulation chamber SAPHIR.

Clouds, photolysis and regional tropospheric ozone budgets. [PDF]

open access: yes, 2009
We use a three-dimensional chemical transport model to examine the shortwave radiative effects of clouds on the tropospheric ozone budget. In addition to looking at changes in global concentrations as previous studies have done, we examine changes in ...

Distribution of hydrogen peroxide and methylhydroperoxide over the Pacific and South Atlantic Oceans [PDF]

open access: yes, 1999
The gas phase hydrogen peroxide and methylhydroperoxide concentrations were measured in the troposphere over the tropical Pacific Ocean as a component of NASA's Global Tropospheric Experiment/Pacific Exploratory Mission-Tropics A field campaign.

The Linkage of Serial Cyclone Clustering in Western Europe and Weather Regimes in the North Atlantic‐European Region in Boreal Winter

open access: yesGeophysical Research Letters, 2023
Extra‐tropical cyclones are an important source of weather variability in the mid‐latitudes. Multiple occurrences in a short period of time at a particular location are denominated serial cyclone clustering (SCC), and potentially lead to large societal ...
