The article briefly describes an optical probe for direct measurements and studies of the vertical distribution of the aerosol component of the atmosphere. The operation principle is based on the measurement of backscattering from a sequence of powerful probing pulses. The analyzed air volume is located at a close (0.5 m) distance from the radiation source. LEDs at 470 nm and 940 nm are used as radiation sources. The probe can be easily integrated with all types of standard aerological radiosondes, meteorological rockets, and having its own navigation module and telemetry system it can also be used in autonomous launches. The results of measurements carried out at the Dolgoprudny aerological station in November 2020, which recorded low values of the aerosol backscattering coefficients in the stratosphere, are presented.
