Tonokura Lab
Machine-translated · View original
A lab that studies how chemical substances in the atmosphere affect the environment.
AboutAbout the lab
Revealing the behavior of chemical substances in the atmosphere.
The Tonokura Lab studies phenomena caused by chemical substances in the atmosphere and their effects on the environment.
Drawing on methods from physical chemistry and spectroscopy, the lab investigates atmospheric components and how they change.
In particular, to understand the mechanisms by which substances harmful to human health transform in the atmosphere, the lab develops measurement instruments and analyzes chemical reactions.
Key terms
- Spectroscopy
- The study of the light that substances emit or absorb, used to determine the type, amount, and properties of a substance
- Column concentration
- The average concentration of a gas in a column of air extending from the ground surface to the top of the atmosphere, reflecting the total amount of that gas in the column
- Photoacoustic method
- A method that measures the faint sound produced when light is shone on a gas, in order to determine properties such as the gas concentration
- Smog chamber
- An experimental apparatus that reproduces chemical reactions occurring in the atmosphere inside a large container so that they can be studied
ResearchResearch themes
Based on approaches from physical chemistry and spectroscopy, the Tonokura Lab seeks to clarify phenomena caused by chemical substances in the atmosphere and their effects on the environment. In particular, to understand how substances harmful to human health behave in the atmosphere and the mechanisms behind that behavior, the lab develops measurement instruments and analyzes chemical reactions.
*Illustrative imageMeasuring trace gases in the atmosphere
The lab measures gases present in the atmosphere in very small amounts. Examples include measuring the column concentration of carbon dioxide at the National Institute for Environmental Studies, measuring methane emitted from faults in Horonobe, and developing instruments that measure carbon dioxide concentration using the photoacoustic method.
*Illustrative imageChemical reactions in the atmosphere
The lab conducts experiments that reproduce atmospheric chemical reactions in a smog chamber, and estimates atmospheric ethylene oxide concentrations using a regional chemical transport model.
