CIMEL

Cimel is a brand name associated with Cimel Electronics, a manufacturer of scientific instruments for atmospheric research. The company is best known for its sun photometers, instruments designed to measure direct solar irradiance across multiple wavelengths in order to derive atmospheric properties such as aerosol optical depth and other related parameters.

CIMEL sun photometers are widely used in global networks for long-term monitoring of atmospheric composition and climate-relevant variables. They are designed for field deployment and automated operation, featuring sun tracking, multi-wavelength optical channels, and data logging. The measurements produced by these instruments support aerosol research, radiative transfer studies, and validation of satellite observations.

In addition to instruments, Cimel may also appear as a surname. There are no widely documented notable individuals with the name Cimel in major reference sources.
