in atmospheric chemistry
https://doi.org/10.1351/goldbook.D01861
A small liquid particle. The size of droplets encountered in the atmosphere extends over a wide range; e.g. liquid @[email protected] solutions which make up the fine particle fraction of continental tropospheric @[email protected] are usually $$2\ \unicode[Times]{x3BC}\text{m}$$ in diameter. Cloud water droplets usually have diameters in the range of $$5-70\ \unicode[Times]{x3BC}\text{m}$$, while rain droplets commonly have diameters ranging from $$0.1-3\ \text{mm}$$.
