Her recent research projects focus on understanding the impact of Arctic sea ice loss on the mid-latitude weather and climate as well as understanding the summer monsoon circulation and its associated troposphere-stratosphere transport.
The detailed study of the ISO reveals its significant relationship with the lower atmospheric MJO suggesting its origin at lower troposphere, and it should be mentioned that such relationship is not prominent in the available limited dataset.
Chung, E.-S., Soden, B. J., Sohn, B.-J. & Schmetz, J. Model‐simulated humidity bias in the upper troposphere and its relation to the large‐scale circulation.
The CRISTA experiment provided global measurements of atmospheric trace gases in the stratosphere and upper troposphere during its second mission in August 1997.
In 2012 the global average mole fraction of HFC-143a was 13.4 ± 0.3 ppt (1σ) in the lower troposphere and its growth rate was 1.4 ± 0.04 ppt yr−1; HFC-32 had a global mean mole fraction of 6.2 ± 0.2 ppt and a growth rate of 1.1 ± 0.04 ppt yr−1 in 2012.
Nevertheless, there is a growing body of evidence for some downward effect of the stratosphere on the troposphere and its weather systems.
Isoprene (C5H8, 2-methyl-1,3-butadiene) is the most abundant VOC emitted by plants and is the focus of considerable current research because of its influence on the troposphere.
Acetone was speciated due to its importance in the upper troposphere.
In the diagram below, that maximum is readily apparent, using a parameter called "lifted index". The little number (minus-9 Celsius over Washington) means rising air would be 18 degrees Fahrenheit warmer than its surroundings, halfway up the troposphere.
Spectroscopic observers found that ammonia and carbon disulfide persisted in the atmosphere for at least fourteen months after the collisions, with a considerable amount of ammonia being present in the stratosphere as opposed to its normal location in the troposphere.
