Water is a major component of ocean and cloud droplets that influences global climate change. However, liquid water does not exist “homogeneously” on the earth. This inhomogeneity includes the air-water interface, where the density of water drops five orders of magnitude in ~1 nm, and the domains of sub-micrometer size naturally formed with other components (e.g., organic solutes) in liquid phases [e.g., Proc. Natl. Acad. Sci. U.S.A., 2012, 109, 18679, Proc. Natl. Acad. Sci. U.S.A., 2014, 111, 623, J. Chem. Phys., 2019, 150, 024702, Environ. Sci. Technol. 2020, 54, 3890.]
Here, we demonstrate some examples of such molecular (10-10 m = angstrom level) inhomogeneity influencing atmospheric physical/chemical processes. We also discuss the possibility that revealing the essential roles of angstrom-level inhomogeneity leads to a new research field.
